# Best AI tools for spreadsheets (2026)

> **In short:** The best AI spreadsheet tools in 2026 are Slaide, Microsoft Copilot in Excel and Google Sheets with Gemini. Slaide builds a live spreadsheet with working formulas from your data quickly, free to start. Microsoft Copilot in Excel is the most powerful for heavy, formula-intensive analysis, while Google Sheets with Gemini is the natural pick for Workspace users building and editing inside Sheets.

AI in spreadsheets now spans two jobs: building a spreadsheet from scratch out of your data, and doing heavy analysis inside an existing one. The best tool depends on which side of that line you're on.

This list leads with Slaide for building spreadsheets from your own material, and is honest that for deep, formula-heavy analysis the established spreadsheet platforms go further. Each entry notes what it's genuinely best at.

### 2. [Microsoft Copilot in Excel](https://www.microsoft.com/microsoft-365-copilot)
