Excel Copilot

Excel Copilot is Microsoft's AI inside Excel: it writes formulas, analyzes data, suggests charts, and summarizes tables directly in the grid. It is powerful and deeply native, but requires a paid Microsoft 365 Copilot license and stays inside the Microsoft ecosystem.

Native inside Excel desktop and web — no extra tool to open
Backed by Microsoft with enterprise security and compliance
Works across Microsoft 365 apps, not just Excel
No free tier — requires paid Microsoft 365 plus the Copilot add-on
Locked to the Microsoft ecosystem; no Google Sheets support
Availability and features vary by plan, version, and region

Kimi Sheets

Kimi Sheets is an agent skill within Moonshot AI's Kimi: describe what you want and it builds a complete Excel workbook — formulas (VLOOKUP/XLOOKUP through nested logic), pivot tables, and auto-formatted charts — which you preview and download. It can clean messy data and pull live data (Yahoo Finance, ArXiv), but it outputs a downloadable file rather than editing your existing workbook, and it has no native Excel/Sheets add-in.

Builds full workbooks — real formulas wired to columns, pivots, charts
Live external data pulls (Yahoo Finance, ArXiv) with auto-cleaning
Low skill barrier — natural language to presentation-ready Excel
Separate web tool that outputs a file — no in-grid editing or add-in
Complex business logic can contain errors; verify before relying on it
