Best AI Tools for Excel in 2026: Tested & Ranked

TL;DR: What You Need to Know

Excel’s own built-in AI is Microsoft 365 Copilot, which now edits your workbook and even runs inside a cell with the new =COPILOT() function. If you want help without a paid Microsoft license, FormulaBot and GPTExcel are the best free formula generators, Numerous.ai brings an =AI() function to both Excel and Google Sheets, and Julius AI or ChatGPT handle full data analysis on an uploaded file. Pick by the job: writing formulas, working inside your cells, or analyzing a dataset.

The best AI tools for Excel at a glance

Here is how the main tools compare on type, which spreadsheets they work with, the free tier, and where paid plans start. Prices and availability change quickly, so confirm on the vendor’s site before paying.

How we picked

We judged each tool on where it works (inside Excel, as an add-in, or as a standalone app), what it does beyond writing formulas, how it handles larger datasets, the free tier, and privacy. We also separated the tools by job, because a formula generator and a full data-analysis assistant solve different problems. We are an independent publisher and do not sell a spreadsheet tool, so none of these picks is our own product.

Does Excel have built-in AI?

Yes. The AI built into Excel is Microsoft 365 Copilot. With a workbook saved to OneDrive or SharePoint, you open the Copilot pane from the Home tab and ask in plain English to clean data, spot trends, write a complex formula, or build a report, no coding needed.

Two newer pieces are worth knowing. Agent mode, sometimes called “Edit with Copilot,” went generally available across web, Windows, and Mac in early 2026, and it can directly edit your workbook: create formulas, build pivot tables, generate charts, and run multi-step tasks, with a built-in choice of model and web search. Microsoft has also added an in-cell =COPILOT() function that lets you call Copilot from inside a cell, the same way you would any formula. It is the most integrated way to use AI in Excel, with the catch that it needs a paid Microsoft 365 Copilot license and works only in Excel, not Google Sheets.

• Best for: Microsoft 365 users who want AI inside Excel with nothing to install.
• Pricing: Microsoft 365 Copilot license, around $30/user/mo; a limited free Copilot Chat exists.
• Skip if: you do not want a paid license, or you work in Google Sheets.

Best AI formula generators for Excel

These turn plain English into a working formula, and explain or debug the ones you already have.

GPTExcel is the most versatile formula tool. It writes and explains formulas, plus SQL queries, VBA and Apps Script, and regex, and it works across Excel, Google Sheets, LibreOffice, and Airtable. Newer features let you chat with your file, turn an image into a table, and generate charts.

• Best for: Formulas plus scripts across several spreadsheet platforms.
• Pricing: Free tier (limited messages); Pro from $9/mo (about $6.30/mo annual).
• Skip if: you want AI working natively inside your cells.

FormulaBot is the best free all-rounder. In one chat tool, with no plugin and no Microsoft subscription, it generates formulas, answers questions about an uploaded spreadsheet, builds charts, and can even create a spreadsheet from a text prompt. You can try it without signing up.

• Best for: A free, no-setup tool that does formulas, analysis, and charts.
• Pricing: Free tier (no login); paid from around $15/mo.
• Skip if: you need it to read external or real-time data beyond your upload.

Ajelix leans toward Excel power users, with a formula generator alongside a VBA script explainer and debugger, a template generator, and SQL tools for both Excel and Google Sheets.

• Best for: Learning and debugging VBA, and building templates.
• Pricing: Free plan; paid from around $20/mo.
• Skip if: you only need occasional formula help.

Best in-spreadsheet AI assistants

These work inside your cells rather than in a separate window.

Numerous.ai adds a simple =AI() function to any cell: write a prompt, drag it down, and apply it across thousands of rows to classify, clean, summarize, or generate text. It works in both Excel and Google Sheets, needs no API key, and caches results to keep costs down.

• Best for: Cell-level AI tasks across many rows in Excel or Sheets.
• Pricing: 7-day trial; Personal $8/mo billed yearly; Pro $24/mo.
• Skip if: you need multi-step analysis, pivot tables, or charts.

GPT for Work is a native add-in with an AI agent that reads your data, runs analysis, and writes the results back, with real bulk processing across large datasets and a choice of models. It works in both Excel and Google Sheets and prices by credit rather than per seat.

• Best for: Spreadsheet-native AI analysis with genuine bulk processing.
• Pricing: Free trial; pay-as-you-go credits from around $29.
• Skip if: you want a fixed monthly subscription.

Claude in Excel is Anthropic’s official sidebar add-in. It reads across multiple tabs, understands how cells and formulas relate, edits with change tracking, and gives cell-level citations so you can trace every answer, which makes it strong for complex financial workbooks.

• Best for: Multi-tab, traceable analysis of complex workbooks.
• Pricing: Add-in free to install; needs Claude Pro from $20/mo.
• Skip if: you need row-by-row bulk processing or Google Sheets.

Best AI tools for data analysis with Excel data

When you want to ask questions of a whole dataset rather than write a formula, these are the picks.

Julius AI is a standalone AI data analyst. Upload an Excel file or connect a database, ask in plain English, and it returns charts, summaries, and statistics, writing and running the code behind the scenes. It offers dozens of chart types, reusable notebooks, and two-way Google Sheets sync.

• Best for: No-code data analysis without a BI platform.
• Pricing: Free tier; paid from around $18/mo.
• Skip if: you want the AI working inside Excel itself.

ChatGPT handles Excel data two ways: upload a file and ask questions in its data-analysis mode, or use the official ChatGPT for Excel add-in to build and analyze the sheet in place. It is the natural pick if you already pay for ChatGPT. For how it compares with other assistants, see our best AI chatbots guide.

• Best for: ChatGPT subscribers analyzing spreadsheets.
• Pricing: Free tier; Plus $20/mo.
• Skip if: you need bulk processing or pivot tables, which the add-in does not yet do.

What is the best free AI tool for Excel?

For genuinely free help, FormulaBot is the easiest start: it needs no login and covers formulas, analysis, and charts in one place. GPTExcel has a free tier too, capped at a set number of messages a month, and Numerous.ai gives a 7-day trial of its in-cell function. Microsoft’s free Copilot Chat can answer Excel questions, but editing your workbook with Copilot needs the paid license. The honest pattern is that free tools handle the occasional formula or one dataset well, while heavy or repeated use pushes you onto a paid plan.

How to choose the right AI tool for Excel

Start with the job. If you just need a formula written or fixed, a free generator like FormulaBot or GPTExcel is enough. If you want AI working inside your cells across many rows, Numerous.ai or GPT for Work fit better. For analyzing a whole dataset, a standalone analyst like Julius or ChatGPT is the right tool. Then weigh three things: whether you use Excel, Google Sheets, or both, since some tools are Excel-only; whether you already pay for Microsoft 365 or ChatGPT, which may give you AI at no extra cost; and how each tool handles your data, which matters for anything sensitive. Many people pair Excel’s built-in Copilot with one free formula tool for quick jobs. Finance teams in particular will find more in our AI tools for finance teams guide.
