How to choose an AI spreadsheet tool

Start with the spreadsheet app you already use: Claude, ChatGPT, Copilot and Gemini all work inside Excel or Google Sheets. Then decide whether you mostly build models, need help with formulas or want answers across several data sources.

• Your work lives in Excel

  Microsoft Excel includes Copilot with Microsoft 365 Personal, at $99.99 a year, and with business plans that bundle Copilot. If you already pay for an AI assistant, its Excel add-in may be all you need. Claude works in Excel on its paid plans, from $17 a month billed yearly, and ChatGPT for Excel runs on every ChatGPT plan, with limited use on Free and Go.

• Your team works in Google Sheets

  Gemini is built into Google Sheets on Workspace Business Standard ($14 per user a month) and higher plans, and on Google AI Pro for individuals. It is not part of Business Starter. ChatGPT for Google Sheets works on any ChatGPT plan, and Claude for Google Sheets has been in public beta on paid Claude plans since October 6, 2026.

• You build or check financial models

  Claude in Excel links each answer to the cells it used and keeps formulas connected when you change inputs, with data connectors such as S&P Global and LSEG. ChatGPT for Excel also links its answers to cells. Our advice: start from a copy of the workbook, and review every change before you share the file.

• You want answers across several data sources

  Better Analyst, the new name for Formula Bot, connects sheets, databases and BI tools, then answers questions in plain English and builds dashboards. It has a free plan, and Starter costs $14 a month billed yearly.
