The best AI for Excel in 2026
The best AI for Excel depends on where you work. Copilot fits teams already on Microsoft 365 Copilot. ChatGPT fits occasional formula help alongside other tasks. GPTExcel fits people who want a free, spreadsheet-only AI that works with any Excel version or Google Sheets and returns workbooks, pivot tables and PowerPoint decks.
Blazing-fast data analysis, on our own engine
GPTExcel doesn't hand your file to a generic spreadsheet library. It runs on its own proprietary Excel engine, built in-house, that reads your workbook and writes native pivot tables, slicers, timelines and charts directly. That's why a full pivot report comes back from one message, ready to open in Excel.
- Proprietary Excel engine
- Native pivots, slicers, timelines, charts
- One message, one finished workbook

Best free AI for Excel: GPTExcel
GPTExcel is built only for spreadsheets and runs on its own proprietary Excel engine, which makes its data analysis blazing fast. Upload an Excel, CSV or a photo of a table and ask in plain English. It writes formulas for Excel, Google Sheets, LibreOffice Calc and Airtable, cleans and edits workbooks, builds native pivot tables, slicers, timelines and pivot charts from a single message, and turns data into editable PowerPoint decks. The free plan needs no credit card, and files are never used to train AI.
Best for Microsoft 365 teams: Copilot in Excel
If your company already has Microsoft 365 Copilot, Copilot works inside the open workbook and across Word and PowerPoint. It needs a plan that includes Copilot, and some features aren't available in every region yet.
Best general assistant: ChatGPT
ChatGPT explains formulas well and has an Excel add-in. It's a good fit when spreadsheet questions are a small part of your day.
Also worth a look: Formula Bot
Formula Bot turns plain English into formulas and analyzes uploaded data, with a free plan to start.
How to choose
- Already paying for Microsoft 365 Copilot and working in current Excel: start with Copilot.

- Need a deck, or a pivot table with slicers, timelines and pivot charts, built from your data in one message: GPTExcel.
- Just want a formula explained now and then: ChatGPT or any of the above.
