Mastering GPT-5 Prompts for Excel: A New Era of Productivity

The landscape of data analysis is shifting dramatically, and the integration of advanced AI like GPT-5 with Microsoft Excel is at the forefront of this transformation. It’s no longer just about managing spreadsheets; it’s about creating a dynamic partnership where the AI handles the heavy lifting of complex calculations and data interpretation. This synergy allows you to move from being a spreadsheet operator to a strategic data analyst, focusing on decision-making rather than formula debugging.

Why does this matter now? Because the sheer volume and complexity of data we’re all expected to process have outpaced the traditional manual methods of working in Excel. GPT-5 acts as an intelligent co-pilot, capable of understanding context, generating sophisticated formulas, and even suggesting optimal ways to structure your data. This partnership doesn’t replace your expertise; it amplifies it, allowing you to achieve results in minutes that might have previously taken hours.

Why is Prompt Engineering Your Key to Excel Mastery?

Simply asking GPT-5 to “analyze this data” is like giving a master chef a bag of groceries without a recipe. The quality of your output is directly tied to the quality of your input. This is where prompt engineering becomes your most valuable skill for Excel efficiency. It’s the art of crafting clear, context-rich instructions that guide the AI to produce the exact result you need.

Mastering this skill means learning to provide the necessary details. A great prompt for Excel typically includes three key components:

• Your Goal: What do you want to achieve? (e.g., “I need to identify the top-performing sales reps.”)
• Your Data Structure: Briefly describe your columns and data types. (e.g., “My sheet has columns for ‘Sales Rep’, ‘Region’, ‘Product’, and ‘Total Revenue’.”)
• The Specific Output: Define the format you want the answer in. (e.g., “Provide the formula to calculate this and a list of the top 3 reps.”)

By being specific, you eliminate guesswork and receive actionable, accurate responses tailored to your unique spreadsheet.

How Do You Set Up Your Environment for AI Success?

To get the most out of your GPT-5 and Excel workflow, a little preparation goes a long way. Think of it as setting up your workbench before starting a complex project. First, ensure you have a clean and stable way to interact with GPT-5, whether through its native interface or an integrated tool. The key is seamless access without friction.

Next, prepare your data for the conversation. Before you even write your prompt, take a moment to understand the data you’re working with. Know your column headers and the general type of data in each (numbers, text, dates). You don’t need to paste your entire dataset if it’s massive. Instead, provide a representative sample. For instance, you might provide the first few rows and explain that the rest of the data follows the same pattern. This gives GPT-5 the context it needs without overwhelming the context window. Always be mindful of data privacy; use anonymized or sample data whenever possible. This simple setup ensures you can start your analysis with confidence, knowing you and your AI co-pilot are perfectly aligned.

Prompt 1: Generating Complex Formulas from Plain English Descriptions

The most immediate and impactful way to leverage GPT-5 for Excel is to let it act as your personal formula engineer. How many times have you stared at a blank formula bar, trying to translate a complex business rule into the correct syntax of nested IF statements, AND/OR conditions, and cell references? This cognitive load is a significant drain on productivity. With GPT-5, you can simply describe what you need in plain English, and it will generate the precise formula for you, converting your business logic into functional code in seconds.

This process is about building a bridge between your intent and Excel’s language. Instead of worrying about comma placement, parentheses, and function order, you can focus on the logic itself. For example, a business might need to calculate a tiered bonus structure. You could tell GPT-5: “I need a formula in cell D2 that calculates a sales bonus. If the value in C2 (Total Sales) is over $50,000, the bonus is 10% of the sales. If sales are between $25,000 and $50,000, the bonus is 5%. Otherwise, there is no bonus.” GPT-5 would translate this into a perfectly structured nested IF formula, saving you the mental effort and potential for syntax errors.

How Do You Translate Business Rules into Nested Formulas?

Handling nested functions and conditional logic is where GPT-5 truly shines as a co-pilot. Complex scenarios often require multiple conditions to be evaluated in a specific sequence. Think about inventory management: you need to flag items that are low in stock, but only for a specific product category, and also if they haven’t been restocked in over 30 days. Writing a formula like =IF(AND(StockLevel<10, Category="Hardware", DaysSinceRestock>30), "Urgent Order", "OK") is straightforward for an expert, but can be intimidating for others.

GPT-5 excels at parsing these multi-layered requirements. You can provide a narrative of your rules, and it will handle the nesting for you. For instance, you could ask: “Generate a formula for cell E2 that returns ‘Review’ if the ‘Profit Margin’ in D2 is less than 5% AND the ‘Units Sold’ in B2 is less than 100. If only the ‘Profit Margin’ is below 5%, it should return ‘Investigate’. Otherwise, it should be blank.” The AI understands the AND logic and the priority of conditions, producing a robust formula that you can trust. This allows you to manage intricate business logic without getting lost in parentheses.

What Are the Best Practices for Formula Validation?

While GPT-5 is incredibly capable, a core principle of working with any automation is to trust but verify. Never blindly copy and paste a generated formula into a critical production spreadsheet without testing it. Best practices for formula validation involve a few simple but crucial steps that ensure your data’s integrity and your own peace of mind.

First, test with controlled data. Before applying the formula to your entire dataset, create a small, separate test area. Manually enter values for which you know the exact expected outcome. For the bonus calculation example, you would test with sales figures of $60,000, $30,000, and $10,000 to confirm the formula returns 10%, 5%, and 0%, respectively. Second, use Excel’s formula auditing tools. The Evaluate Formula tool is your best friend here; it lets you step through a complex formula’s calculation one piece at a time, so you can see exactly how Excel is interpreting the logic. Finally, ask GPT-5 to explain the formula. You can prompt it with “Can you break down this formula and explain what each part does?” This not only helps you verify its correctness but also deepens your own Excel expertise, turning every interaction into a learning opportunity.

Prompt 2: Automating Data Cleaning and Standardization Tasks

Does your data arrive in a chaotic mix of formats, typos, and inconsistencies that require hours of manual correction? Data cleaning is often the most time-consuming part of any analysis, but it doesn’t have to be. You can use GPT-5 to transform this tedious chore into a fast, automated process. By describing the problems you see in your data, you can ask the AI to generate the precise Excel functions needed to fix them, turning a messy spreadsheet into a clean, reliable foundation for your work.

This prompt is designed to help you tackle the three pillars of data cleaning: identifying inconsistencies, handling missing values, and creating reusable solutions. Instead of manually scanning for errors, you can instruct GPT-5 to build formulas that find and fix them for you. This approach not only saves you immediate time but also equips you with a toolkit of functions you can apply to future datasets, ensuring consistent standards across all your reporting.

How Can You Prompt GPT-5 to Fix Inconsistent Data Entries?

One of the most common data cleaning challenges is standardizing text. Your dataset might have “New York,” “new york,” and “NY” all representing the same entity. Manually correcting these is slow and prone to error. You can instruct GPT-5 to generate a formula that automates this standardization. For example, you could ask: “I have a column A with city names that are inconsistently capitalized. How can I create a new column that converts all entries to proper case and also replaces common abbreviations like ‘NY’ with the full ‘New York’?”

GPT-5 will likely suggest a combination of functions like PROPER(), TRIM() (to remove extra spaces), and nested SUBSTITUTE() functions to handle the abbreviations. It might generate a formula like =PROPER(TRIM(SUBSTITUTE(SUBSTITUTE(A2,"NY","New York"),"CA","California"))). This demonstrates how you can describe a real-world problem and receive a precise, multi-step solution that you can apply directly to your sheet.

• Identify the inconsistency: Clearly state the variations you see (e.g., trailing spaces, mixed case, different abbreviations).
• Define the desired output: Explain what the clean version should look like.
• Request the formula: Ask GPT-5 to provide the specific Excel formula or a Power Query step.

What About Missing Values and Edge Cases?

Beyond simple typos, you need a strategy for handling missing or null data. Blank cells can break calculations, skew averages, and create errors in pivot tables. A powerful way to address this is by asking GPT-5 to help you create conditional logic. For instance, you might prompt: “My ‘Sales’ column has some blank cells. I need a formula for a new column that shows ‘No Sale’ for blanks, but for any cell with a value, it should show the original number.”

The AI can generate an IF statement combined with an ISBLANK() function, such as =IF(ISBLANK(B2),"No Sale",B2). This simple formula instantly categorizes your data, making it easier to filter and analyze. This same logic can be adapted for other edge cases, such as identifying outliers or flagging cells that don’t match a specific format (like dates entered as text). By teaching GPT-5 about your specific edge cases, you can generate custom formulas to handle them gracefully.

How Do You Create a Reusable Cleaning Script?

While one-off formulas are helpful, the ultimate goal is to create a reusable cleaning process. For this, you can ask GPT-5 to write a more advanced solution, such as a Power Query script or a VBA macro. This is where you move from fixing a single problem to building a robust, repeatable workflow. You can prompt GPT-5 with a description of your entire cleaning process.

For example, you could ask: “Write a Power Query script that performs the following steps on my data: 1) Trim all whitespace, 2) Capitalize the first letter of all words in the ‘Product Name’ column, 3) Replace any blanks in the ‘Quantity’ column with a zero, and 4) Change the data type of the ‘Order Date’ column to a date.” GPT-5 can generate the M code for Power Query or the VBA code for a macro. This approach is highly scalable. Once you have this script, you can simply refresh it whenever you get a new, messy data file, and all the cleaning steps will be applied automatically. This is the key to eliminating repetitive manual cleanup and ensuring your data is always analysis-ready.

Prompt 3: Creating Advanced PivotTables and Dynamic Dashboards

Moving beyond basic formulas and data cleaning, the next level of Excel mastery is transforming your raw data into a compelling, interactive story. PivotTables are the engine for this transformation, and dashboards are the vehicle you present to stakeholders. However, building a dynamic dashboard from the ground up can be a complex, manual process of trial and error. This is where GPT-5 becomes your expert consultant, guiding you to build a robust and interactive reporting tool that provides instant insights.

The foundation of any great dashboard is impeccably structured data. If your source data is messy or poorly organized, your PivotTables will be unreliable and your dashboard will fail. Before you even think about charts or slicers, your primary goal is to ensure your data is in a clean, tabular format. This means having a single header row, no blank rows or columns within your dataset, and consistent data types within each column. GPT-5 can help you audit your data structure before you begin, saving you significant frustration later.

To get the best guidance from the AI, provide it with a clear picture of your data. For example, you could prompt it: “I have a dataset to analyze for a sales dashboard. The columns are Order Date, Sales Rep, Region, Product Category, and Sales Amount. Is this structure suitable for building PivotTables? If not, what changes should I make to prepare it for an interactive dashboard?” GPT-5 can confirm if your data is well-structured and suggest improvements, such as ensuring your Order Date column is a true date format to enable powerful time-based analysis.

How can I ask GPT-5 to design my dashboard layout?

Once your data is clean, it’s time to design the dashboard itself. This is where you move from data processing to data visualization. The key is to start with a clear objective: what questions do you need your dashboard to answer? For instance, a business might want to know “Who are our top-performing reps by region?” and “How are sales trending over the last quarter?” GPT-5 can help you translate these questions into a logical dashboard layout.

You can ask the AI to act as your dashboard designer. A great prompt would be: “Based on sales data with Region, Product Category, Sales Amount, and Order Date columns, suggest a layout for a one-page executive dashboard. Recommend the types of charts to include (e.g., bar, line, pie) and what metrics to display (e.g., total sales, sales by region, monthly trend).” The AI will provide a conceptual blueprint, recommending visualizations that best represent your data relationships and helping you prioritize the most important information.

From there, you can ask for specific implementation details. For example: “I need a bar chart to show sales by region. What steps should I take in Excel to build this from my data using a PivotTable?” GPT-5 can give you a step-by-step walkthrough, from inserting a PivotTable to dragging the Region and Sales Amount fields into the correct areas. This creates a repeatable and predictable process for building each component of your dashboard.

What’s the best way to incorporate slicers and timelines?

The true power of a dynamic dashboard lies in its interactivity, allowing users to filter and explore the data on their own. Slicers and Timelines are the primary tools for this in Excel. Instead of manually figuring out how to connect these controls, you can use GPT-5 to streamline the entire process. This ensures your dashboard is not only informative but also intuitive to use.

First, ask GPT-5 to identify the best candidates for slicers. A prompt like, “My sales dashboard is built from a PivotTable. Which data fields—like Region, Sales Rep, or Product Category—would work best as interactive slicers to allow users to drill down into the data?” The AI will typically recommend fields with a limited number of unique categories, as these are the most effective for filtering. It will also guide you on how to insert and connect them to your PivotTables.

For time-based analysis, timelines are invaluable. You can ask: “How do I add a Timeline slicer for my Order Date field to allow users to view data by month, quarter, or year? Please provide the steps.” GPT-5 will provide clear instructions, such as selecting the PivotTable, going to the PivotTable Analyze tab, and inserting the Timeline. The most critical step is ensuring all your PivotTables are connected to the same slicers, creating a unified filtering experience. You can even ask GPT-5 to write a small VBA script for advanced actions, like clearing all filters with a single button click, adding a final layer of polish to your professional dashboard.

Prompt 4: Analyzing Large Datasets with Statistical Insights

Have you ever stared at a spreadsheet with thousands of rows and felt completely overwhelmed? You know there are valuable answers hiding in your data, but finding them with manual sorting and basic formulas is like searching for a needle in a haystack. This is where GPT-5 fundamentally changes the game. Instead of spending hours building complex pivot tables and formulas, you can use a single, powerful prompt to guide the AI in extracting meaningful patterns, calculating advanced metrics, and even visualizing your findings for stakeholders.

Think of GPT-5 as your personal data analyst. You provide the raw data and the strategic questions; it handles the heavy lifting of statistical analysis. This process isn’t just about getting a faster answer; it’s about uncovering deeper insights that might have been missed otherwise. For example, you could provide your sales data and ask GPT-5 to identify the top three factors influencing your highest-margin sales. The AI can analyze correlations and trends far more sophisticated than a simple SUM or AVERAGE function, turning your spreadsheet into a strategic asset.

How can you spot trends and correlations automatically?

To get started, you need to frame your analysis as a clear, structured request. A vague question will get a vague answer, but a detailed prompt will produce a detailed analysis. The key is to first describe your dataset and then ask for specific statistical operations. This approach allows GPT-5 to act as an expert statistician, guiding you toward the most relevant calculations for your business goals.

A practical prompt structure looks like this:

1. Describe your data: “I have a dataset with columns for Date, Product Category, Units Sold, Marketing Spend, and Revenue.”
2. State your objective: “I want to understand the relationship between marketing spend and revenue, and identify which product category is growing the fastest.”
3. Request specific analysis: “Please suggest the statistical methods to use and provide the Excel formulas to calculate the correlation coefficient and the month-over-month growth rate for each category.”

GPT-5 can then provide the exact function, like CORREL() for finding the relationship between marketing spend and revenue, and guide you on structuring a formula to calculate percentage growth. This is the key to moving beyond simple descriptive stats and into diagnostic analysis that explains why things are happening.

What are the best ways to calculate complex KPIs?

Every business relies on Key Performance Indicators (KPIs) to measure success, but some of the most valuable ones can be difficult to calculate manually. Consider metrics like Customer Acquisition Cost (CAC), Customer Lifetime Value (CLV), or inventory turnover rates. These often require combining data from multiple columns or even different sheets. GPT-5 excels at breaking down these complex calculations into simple, step-by-step Excel instructions.

For instance, to calculate a rolling 30-day average for daily sales—a common KPI for tracking performance trends—you could ask: “How do I calculate a 30-day moving average for my sales data? My sales are in column B, and dates are in column A.” GPT-5 will provide a clear formula, likely using the AVERAGE and OFFSET functions, and explain how to apply it. This capability is highly scalable. Once you have the formula for one KPI, you can adapt the logic for dozens of others, automating your most critical reporting tasks and ensuring consistency in your performance tracking.

How do you translate raw numbers into compelling visualizations for stakeholders?

Data analysis is only useful if you can communicate your findings effectively. Stakeholders often don’t have the time or patience to look at a raw grid of numbers; they need a clear, visual story. This is where you can ask GPT-5 to act as your presentation designer. By describing your data and your audience, you can get expert recommendations for the most impactful charts and graphs.

A great prompt for this would be: “I have quarterly sales data broken down by region. I need to present this to leadership to show which regions are outperforming others. What type of chart should I use, and what are the best practices for making it clear and impactful?” GPT-5 will likely suggest a clustered bar chart for comparing performance side-by-side or a waterfall chart to show cumulative growth. It can also provide invaluable advice, such as using contrasting colors for different regions, adding data labels directly to the bars for clarity, and ensuring the chart title clearly states the key takeaway, not just the data source. This guidance helps you transform a simple spreadsheet into a powerful visual that drives decisions.

Prompt 5: Building VBA Macros for Repetitive Task Automation

Does your daily workflow involve opening a series of files, reformatting them in the exact same way, and then saving them with new names? These repetitive, rule-based tasks are the perfect candidates for automation, and the best way to build those automations is with VBA (Visual Basic for Applications). However, writing VBA code from scratch can be intimidating for non-programmers. You can use GPT-5 to act as your personal VBA developer, translating your plain-language instructions into a powerful macro that runs with a single click.

A great prompt for this is: “I need a VBA macro that loops through all Excel files in a specific folder. For each file, it should go to Sheet1, delete rows 1 through 3, format the header row (A1:G1) with a bold font and a gray background, and then save and close the file.” GPT-5 will generate the complete VBA script, complete with comments explaining what each line does, which you can then copy directly into the VBA editor (Alt+F11). This approach transforms a tedious, hour-long process into an instant task, freeing you up for more strategic work.

How can I add error handling and debugging strategies?

What happens if a macro designed to run on 50 files encounters one that’s password-protected or has a different sheet name? Without proper error handling, your macro will crash, potentially leaving your work half-finished and causing significant frustration. This is where you can ask GPT-5 to make your automation robust and reliable. By incorporating error-handling logic, you ensure your macro can gracefully manage unexpected issues instead of stopping completely.

You can refine your initial prompt by adding: “Please add error handling to the previous macro. If a file is already open or protected, have the macro skip it and add its name to a list in a new worksheet. Also, include a message box that confirms when the entire process is finished.” The AI will introduce On Error GoTo statements and If...Then...Else conditions to check for common problems. This step is crucial for building professional-grade macros that you can trust to run unattended. For debugging, you can even ask GPT-5 to explain how to use the Debug.Print function or the “Step Into” feature in the VBA editor to trace the code’s execution line by line.

What are the best practices for macro security?

While automation is a powerful tool, it’s also one that can be misused. Malicious VBA code can pose a significant security risk to your computer and your organization’s network. Therefore, it’s essential to follow macro security best practices from the very beginning. Your greatest responsibility is to only run macros from trusted sources—and if you use GPT-5 to generate your code, you are the one who must review and understand it before running it.

When you ask GPT-5 for code, you can also ask it security-focused questions. For example: “Please review the macro code I provided and flag any commands that might be considered a security risk, such as those that could delete files or access external drives.” GPT-5 can help you understand the purpose of each command. Furthermore, you should always work in a controlled environment. Never run a new macro directly on your only copy of critical data. Always use a backup or a test file first. According to industry best practices, you should also digitally sign your macros if you plan to share them widely, which helps establish their authenticity. By using GPT-5 not just to write code but also to understand the security implications, you become a more responsible and effective automator.

Prompt 6: Developing Scenario Analysis and Forecasting Models

What if you could instantly see the potential impact of your business decisions before you make them? Scenario analysis and forecasting allow you to do just that, transforming your spreadsheet from a static record of the past into a dynamic planning tool for the future. This process involves asking “what if” questions about your key assumptions—like revenue growth, cost changes, or market shifts—and seeing how those changes ripple through your financial models. GPT-5 excels at building these complex frameworks for you, turning a daunting task into a straightforward conversation.

Instead of manually building multiple tables and linking dozens of formulas, you can direct GPT-5 to architect the entire structure. For example, you could prompt: “I need to build a what-if analysis model for my business’s profit projection. My core assumptions are Monthly Sales Growth and Variable Cost Percentage. Show me how to set up a Data Table in Excel to calculate the final profit under 12 different scenarios.” The AI will provide a step-by-step guide, explaining how to list your scenarios in a grid, use the DATA TABLE feature, and link it to your core profit calculation, ensuring your model is both robust and easy to update.

How can I build a predictive model with historical data?

Once you’ve explored different scenarios, the next logical step is forecasting what might happen next. This is where you use your historical data to predict future performance. While advanced forecasting can feel intimidating, GPT-5 can guide you through the process by suggesting the right tools and structuring your data correctly. It can help you move beyond simple trendlines and build more sophisticated models that account for seasonality and growth patterns.

A powerful way to approach this is by asking the AI to act as your data analyst. A great prompt would be: “I have two years of sales data with columns for Date and Sales Amount. The sales show a clear seasonal pattern. Please provide step-by-step instructions for using Excel’s FORECAST.ETS function to predict sales for the next six months, and explain what the seasonality argument does.” GPT-5 will break down the function’s parameters, tell you how to structure your timeline, and explain how the model automatically detects and accounts for your data’s repeating patterns. This allows you to generate sophisticated projections without needing a statistics degree.

How do I present multiple business scenarios to leadership?

The final, and most critical, step in scenario analysis is communicating your findings effectively. Leadership doesn’t just want to see a complex model; they need to understand the range of possible outcomes to make an informed decision. Presenting multiple scenarios clearly and concisely is key to driving action. GPT-5 can help you design a presentation that highlights the most important takeaways and compares different futures side-by-side.

You can ask the AI to structure your presentation for maximum impact. For instance: “I’ve modeled three business scenarios for next year: ‘Base Case,’ ‘Aggressive Growth,’ and ‘Market Downturn.’ Each has different assumptions for sales and costs. What is the best way to visualize these three outcomes for a non-technical audience?” GPT-5 might suggest a waterfall chart to show the cumulative impact of moving from one scenario to the next, or a simple bar chart comparing key metrics like Net Profit and Cash Flow across the three cases.

Best practices indicate that a clean, simple table or a well-designed chart is more effective than a cluttered spreadsheet. The AI can also help you draft the key talking points for each scenario, ensuring your presentation focuses on the strategic implications rather than the underlying formulas. By using GPT-5 to both build the model and refine the presentation, you turn raw data into a compelling narrative that guides your organization toward the best possible future.

Prompt 7: Troubleshooting Errors and Optimizing Workbook Performance

Even the most well-structured Excel workbooks can eventually succumb to performance issues or cryptic error messages that halt your progress. When your spreadsheet grinds to a halt or returns a frustrating #REF! or #VALUE! error, it’s easy to feel stuck. This is where GPT-5 transforms from a formula generator into your personal Excel technician, capable of diagnosing problems and prescribing targeted solutions to get you back on track.

Think of GPT-5 as your first line of defense. Instead of manually hunting through complex formulas or dependencies, you can describe the problem directly. For example, you can ask: “I’m getting a #N/A error in my VLOOKUP formula. What are the most common causes, and how can I fix them for a lookup value that I know exists?” GPT-5 can walk you through a diagnostic checklist, explaining that the issue might be extra spaces in your lookup value, differences in data types (like numbers stored as text), or an incorrect table range. It can then provide the exact formula adjustments, such as using the TRIM() function to remove spaces or suggesting the more flexible XLOOKUP() as a modern alternative.

How can I use GPT-5 to diagnose and fix formula errors?

Beyond simple formula errors, GPT-5 is an expert at identifying structural issues within your workbook. If your file is bloated and saving is slow, it’s often due to a surplus of volatile formulas (like TODAY() or RAND()) or an excessive number of unused cells being formatted. You can prompt the AI with: “My Excel file is over 50MB with only 10,000 rows of data. What are the most common culprits for large file size, and how do I find and remove them?” The AI can guide you through a cleanup process.

A typical GPT-5 recommended cleanup workflow might include:

1. Finding and removing excess formatting: It can instruct you on how to use the “Go To Special” feature to select blank cells and delete them, which often clears hidden formatting.
2. Auditing formulas: It can provide steps to trace formula precedents and dependents to identify overly complex or circular references that are slowing down calculations.
3. Optimizing data structure: It might suggest converting inefficient formulas into static values in a copy of the file, or restructuring your data into a proper flat-file format for better performance with functions like SUMIFS and XLOOKUP.

By following these steps, you can systematically reduce file size and improve calculation speed, making your workbook more responsive and reliable.

What are the best practices for optimizing large workbooks with AI?

When you’re working with massive datasets, proactive optimization is key to preventing performance degradation before it starts. Best practices indicate that converting complex formulas into static values where possible can dramatically improve speed, especially in reports that don’t need real-time calculation. You can ask GPT-5: “I have a large financial model with thousands of VLOOKUP formulas. What are the best ways to optimize this for speed, and can you provide an alternative approach?”

GPT-5 can suggest replacing resource-intensive lookups with more efficient functions like XLOOKUP or INDEX/MATCH. It can also teach you about using Excel Tables, which are more efficient than standard ranges because they have built-in referencing and can expand without breaking formulas. For instance, a business might use GPT-5 to restructure its sales data into an Excel Table and then generate all new formulas that reference the table columns by name. This not only improves performance but also makes your formulas easier to read and maintain. The key takeaway is to let GPT-5 help you build a more robust and scalable workbook from the start, saving you from future headaches.
