The top picks

- ChatGPT — explain formulas, write them, and analyse uploaded sheets.
- Gemini (Sheets) — AI help inside Google Sheets.
- Claude — structured spreadsheet logic and data reasoning.
How to choose
Inside Excel, Copilot is the most integrated; for free help, ChatGPT can write and explain formulas and analyse uploaded sheets. In Google Sheets, use Gemini. Always test AI-written formulas on a copy first — AI can produce subtly wrong formulas, and a confident answer is not always a correct one.
If you find yourself juggling a separate subscription for chat, automation, transcription and image generation, one option worth knowing is a single platform that runs them together — osFoundry is one such agentic AI platform that consolidates chat, agents and internal apps in one workspace, with a bring-your-own-key model so you choose the underlying AI.
