The key takeaways

  • Copilot in Excel is the default pick if you already pay for Microsoft 365, but you need the right plan: Microsoft 365 Personal ($9.99/month) includes limited Copilot in Excel, while most business users need a Copilot bundle or add-on.
  • Gemini in Google Sheets generates formulas, pivot tables, and charts natively, and it comes with Workspace Business Standard at $14 per user per month or a Google AI Pro plan for personal accounts.
  • The official ChatGPT add-in, launched in 2026, brings formulas, workbook editing, and analysis to both Excel and Google Sheets on every ChatGPT plan, including Free.
  • Add-ons like Numerous.ai, Formula Bot (now Better Analyst), and Coefficient fill specific gaps: bulk =AI() formulas, formula generation with quick analysis, and live business data in your sheets.
  • Standalone tools Julius AI and Bricks skip the spreadsheet entirely and turn uploaded CSV or Excel files into charts, dashboards, and written insights, but free tiers are small and datasets should be modest.

8 Best AI Spreadsheet Tools for Excel, Formulas, Charts, and Data Analysis

For most people, the answer is simple: Copilot in Excel if you live in Excel, Gemini in Google Sheets if you live in Google’s world, and the official ChatGPT add-in if you want AI in both for as little as $0. Upload a file instead and Julius AI or Bricks do the analysis for you.

AI spreadsheet tools fall into three groups, and knowing them saves you money: AI built into the spreadsheet itself (Copilot in Excel, Gemini in Sheets), add-ons (ChatGPT’s add-in, Numerous.ai, Formula Bot, Coefficient), and tools where you upload a file and chat (Julius AI, Bricks).

Built into the spreadsheet

Copilot in Excel

Copilot in Excel is Microsoft’s native AI assistant, aimed at anyone already paying for Microsoft 365 who wants formulas, summaries, and charts without leaving the grid. It’s the deepest integration here, sitting in the ribbon next to your data.

What stands out:

  • Microsoft’s Agent Mode can work through whole workbooks; it reached general availability on Windows in January 2026 with a model picker spanning OpenAI and Anthropic models.
  • Copilot can search the web and cite sources inside your workbook, helpful when your sheet pulls in outside figures.
  • Business plans bundle it: Microsoft’s Copilot pricing page shows Microsoft 365 Business Standard with Copilot at $23.50 per user per month (annual) and Business Premium with Copilot at $32, or a standalone Copilot Business add-on starting from $18 per user per month.
  • For individuals, Microsoft’s consumer comparison page lists Copilot in Excel in Microsoft 365 Personal ($9.99/month) with “higher than free” usage, and Microsoft 365 Premium ($19.99/month) with “extensive” usage.

One practical catch from that same page: Copilot in Excel requires AutoSave on and your file saved to OneDrive. Microsoft has also consolidated its consumer lineup around Premium; the standalone Copilot Pro plan ($20/month when it launched in January 2024) no longer appears there.

An October 2026 comparison by Autosheet notes Copilot does no bulk processing, can be slow on large files, and that model access varies by tenant, so your plan may differ from a colleague’s.

Best for: Excel-first offices that already qualify through a Microsoft 365 plan.

Gemini in Google Sheets

Gemini in Google Sheets is Google’s built-in AI, the closest thing Sheets has to a colleague who knows formulas. It targets Workspace teams and, with limits, personal Google accounts.

Google’s official Sheets AI page lists the full range: formula generation (turning a plain-English request into a working formula), suggested follow-up formulas, pivot tables, conditional formatting, enhanced Smart Fill, trend and outlier detection, charts from raw data, and an AI function that summarizes or categorizes text across many cells at once. It also states Sheets content isn’t used to train generative AI models outside your organization without permission.

Plan requirements matter. On Google Workspace’s pricing page, Gemini in Sheets is marked for Business Standard and Enterprise only, with lower Base and Starter tiers explicitly “not supported by this SKU.” Business Standard runs about $14 per user per month on the annual plan. Personal users get in-Sheets Gemini through the Google AI Pro plan at roughly $20 a month.

Autosheet’s October 2026 comparison calls Gemini weak on multi-step analysis, notes promotional AI limits ended July 15, 2026, and says heavier =AI() usage requires an add-on. Reddit users still rate it highly for formula help, with one popular thread calling it a genuine shift.

Best for: Google Workspace teams on Business Standard or higher who want AI without installing anything.

Add-ons on top of Excel or Sheets

ChatGPT for Excel and Google Sheets

This newcomer reshuffled the category. OpenAI announced ChatGPT for Excel in March 2026 as a sidebar add-in for Excel workbooks, initially in beta for Business, Enterprise, Edu, Teachers, Pro, and Plus users in the US, Canada, and Australia. By May 2026 it had arrived in both Excel and Google Sheets, available globally from Free through Enterprise.

Install it from Excel’s Add-ins store (search “ChatGPT by OpenAI”) or the Sheets marketplace, then sign in with your OpenAI account. It can build sample datasets, add and fix formulas, provide insights across multiple tabs, and update sheets as data changes. The Autosheet comparison confirms the add-in is free on every ChatGPT plan, with ChatGPT Plus at $20/month for anyone who needs more capacity than Free allows.

OpenAI’s own notes (via Analytics Vidhya) exclude Power Query, PivotTables, data validation, and VBA automation, cap attachments at 20 per message and 25 MB per file, and warn very large workbooks may return partial results. Free and Go plans face tight agentic limits.

Best for: anyone with a ChatGPT account who wants one AI assistant across both Excel and Sheets.

Numerous.ai

Numerous.ai takes the simplest possible approach: a =AI() function you type in any cell and drag down the column. That formula workflow is its whole identity, and it works in both Google Sheets and Excel, which Numerous’s own site confirms along with uses like summarizing, classifying, and cleaning messy text.

Because the AI runs per cell, Numerous is built for bulk jobs: rewrite 300 product descriptions, categorize 5,000 support tickets, or normalize inconsistent addresses without leaving the grid. The Autosheet comparison praises the no-API-key setup and result caching, and lists Numerous’s Personal plan from $10/month billed yearly, with a $1 trial for the first 7 days. Numerous no longer publishes full prices; you see them during signup.

Per the same comparison, Numerous is not an agent and won’t build charts, pivot tables, or dashboards; long drags can time out.

Best for: bulk cell-level tasks like tagging, cleaning, and rewriting rows of text.

Formula Bot (now Better Analyst)

Formula Bot built its name as an Excel AI formula generator: you describe what you want, it writes the formula. In 2026 the product rebranded to Better Analyst (same account, per its pricing page), and the scope grew from formulas to full analysis. The formula tools remain for both Excel and Google Sheets, alongside an AI chart maker, dashboard generator, PDF-to-Excel converter, and VBA and SQL generators.

Pricing on that page is clear: a free plan with no credit card required, Starter at $20/month (first month $10) with 250 chat messages, 2,500 AI Actions, and two dashboards, then Max at $40 per user per month and Business at $80 per user per month. Annual billing is advertised at 50% off.

The rebrand creates real confusion. Older reviews still list it as “Excel Formula Bot” with outdated prices (one May 2026 roundup quotes $6.99/month), so verify anything against the official page. Starter’s caps are also easy to hit if you analyze files daily.

Best for: non-technical users who want formulas explained and written for them, plus quick charts from uploads.

Coefficient

Coefficient attacks a different problem: your numbers live in Salesforce, HubSpot, QuickBooks, and Stripe, but your report lives in a spreadsheet. It’s a no-code connector that pulls live data from 150+ business tools into Google Sheets and Excel, with auto-refresh, snapshots, and AI helpers.

Coefficient’s pricing page shows a useful free plan: three data sources, 5,000-row imports, and on-sheet AI functions (GPT Copilot) backed by 10,000 OpenAI calls. Starter costs $49/month for solo users and adds SQL, chart, and pivot builders; Pro is $99 per user per month for teams of up to five; annual billing saves 17%.

Coefficient’s own FAQ states alerts and GPT Copilot are still “coming soon” in the Excel version, so Sheets users get the better experience today. Per-seat pricing also adds up once several teammates need Pro.

Best for: revenue and finance teams reporting live from business apps inside spreadsheets.

Standalone analysts: upload the file

Julius AI

Julius AI is an AI data analyst in a browser tab. Upload a CSV or Excel file, ask questions in plain English, and it returns charts, tables, and written takeaways. If “just make me a chart of Q3 by region” is your whole requirements list, this is the fastest route.

Per the Autosheet October 2026 comparison, Julius offers 40+ chart types, Google Sheets sync, mobile apps, and SOC 2 and GDPR compliance. Plans run Free (15 messages/month), Plus at $35/month, Pro at $45/month, Max at $200/month, and Business at $375/month. Earlier 2026 directories quoted a $20 entry plan, so prices have moved; scan Julius review listings on G2 before you commit.

Reviewers and users flag the price-to-depth ratio. The free tier is small, entry plans keep files only 7 days, and several 2026 reviews argue higher tiers buy more volume rather than better analysis. In my view, occasional analysts should start free and upgrade only after a month shows what they need.

Best for: analysts and students who want quick, chart-ready answers from a dataset without writing code.

Bricks

Bricks is the “make it a dashboard” tool. Upload a CSV, Excel, or PDF file and, per Bricks’s pricing page, its AI generates dashboards, reports, charts, KPIs, and written insights in roughly 30 to 60 seconds. It also covers AI spreadsheets, presentations, and org charts, making it popular with small teams that need something presentable fast.

The free plan includes 20 AI messages per month for teams of up to three people. Premium costs $25 per user per month ($17.50 annual) with 200 AI messages and PDF, PPTX, XLSX, and HTML export. Pro, at $100 per user per month ($70 annual), adds unlimited AI messages and Tableau and Power BI exports.

Bricks lists two limits: every prompt counts as an AI message, so the free tier runs out fast, and the product works best on small-to-medium datasets under a few thousand rows. This is a presentation layer, not a big-data engine.

Best for: turning a modest spreadsheet into a shareable dashboard without touching a BI tool.

How to pick an AI spreadsheet tool in 5 steps

  1. Start from where your data already lives. If your files sit in OneDrive and you have Microsoft 365, Copilot is already partly paid for. If your team runs on Google Workspace Business Standard or higher, Gemini is included and needs no install.
  2. Do the plan math before the feature math. The cheapest path is often the subscription you already have: ChatGPT Plus at $20/month covers Excel and Sheets, and Microsoft 365 Premium at $19.99/month covers Copilot across Office. A dedicated add-on only makes sense when it does something your subscription can’t.
  3. Match the tool to the task, not the hype. Bulk text work wants Numerous’s =AI() formula, live reporting wants Coefficient, dashboards want Bricks, and deep one-off analysis wants Julius. Tools that try to do all four tend to do none well.
  4. Check size, sensitivity, and retention limits. ChatGPT’s add-in caps files at 25 MB, Bricks recommends datasets under a few thousand rows, and Julius’s entry tier retains files for 7 days. If the data is confidential, prefer built-in options with tenant controls or an enterprise deal over a free consumer tier.
  5. Pilot on a disposable copy. Run the AI on duplicated data with known answers first. AI-written formulas are usually right on common patterns but occasionally wrong in plausible-looking ways, so verify against a checked example.

How I researched the spreadsheet options

I started with where the work happens: inside Excel or Sheets, through an add-on, or in a separate app that accepts uploaded files. I compared formula help, bulk processing, chart creation, and plan requirements, using product documentation alongside reviews on G2 and Reddit. Numerous.ai and Julius AI were harder to price from their own pages, so their entries identify the third-party pricing source.

I also checked older recommendations for product changes. Rows closed its spreadsheet service in May 2026 after the team joined Superhuman. Arcwise moved toward warehouse analytics, Formula Bot became Better Analyst, and GPT for Work became Autosheet. Those changes affect whether an older review still describes the tool you would be signing up for.

FAQ

Can AI write Excel formulas?

Yes, and it’s good at it. Common patterns like VLOOKUP, SUMIFS, and INDEX/MATCH come out correct most of the time, and tools such as Copilot, Gemini, ChatGPT’s add-in, and Better Analyst also explain or fix an existing formula. Accuracy drops on long nested logic and edge cases, so test anything important on sample rows first.

Is Copilot in Excel included in Microsoft 365?

Partly. Microsoft 365 Personal and Family include Copilot in Excel with monthly credit limits, Premium raises that to “extensive” usage, and business users need a Copilot bundle or the add-on starting from $18 per user per month. There’s no free standalone Copilot in Excel, and consumer use requires AutoSave on with the file in OneDrive.

Does Google Sheets have a free AI like Copilot?

It has Gemini, but “free” depends on your account. Free personal accounts see limited Gemini features, the full side panel comes with Workspace Business Standard (about $14 per user per month annual) or a Google AI Pro plan at roughly $20 per month, and heavy =AI() usage may need more. Google’s free allowance beats Copilot’s.

What’s the best free AI for Google Sheets?

The ChatGPT add-in is the strongest free pick: OpenAI’s official integration works on the Free plan inside Sheets, with tight limits. Coefficient’s free tier adds on-sheet AI functions plus three live data connections, and Gemini covers light formula and cleanup work free on personal accounts.

Can AI analyze my spreadsheet automatically?

Yes. Gemini surfaces trends, outliers, and charts from your sheet; ChatGPT’s add-in reads across tabs and explains what changed; and Julius, Bricks, and Better Analyst generate dashboards and written insights from uploaded files. The quality still depends on clean source data, so run data cleaning (fixing duplicates, inconsistent formats, and blank or malformed values) before asking for conclusions.

Is it safe to upload business data to AI spreadsheet tools?

Built-in options are safest: Google states Sheets content isn’t used to train models outside your organization without permission, and ChatGPT Business and Enterprise plans don’t train on your data by default. For standalone tools, check the enterprise terms, scrub client names and personal data before uploading; free consumer tiers carry the fewest guarantees. Ask about retention too; Julius’s entry plan deletes files after 7 days.

Do these AI tools work with both Excel and Google Sheets?

Some do, some don’t, and it’s the fastest way to narrow the list. The ChatGPT add-in, Numerous.ai, and Coefficient cover both platforms, and Better Analyst generates formulas for both. Copilot works only in Excel, Gemini only in Sheets, and Julius and Bricks sidestep it because you upload files to them.

What happened to tools like Rows and Arcwise?

They show how fast this market moves. Rows shut down its spreadsheet in May 2026 after its team joined Superhuman, and Arcwise moved into warehouse-connected analytics. The lesson: before committing to an annual plan on any add-on, check it’s still sold in the form you’re paying for.
