Generate Excel formulas with AI
Describe the result you want in plain English — which cells or ranges are involved and what you're trying to calculate — and the tool writes a working Excel formula for you. It's the same AI formula assistant built into Excel Studio, just without needing to open a workbook first.
Fix an Excel formula
Paste a formula that's returning an error or the wrong result, optionally describe what's going wrong (like #N/A or #VALUE!), and get a corrected formula back along with a plain-language explanation of what was wrong.
Understand an Excel formula
Paste any formula — your own, or one you inherited from someone else's spreadsheet — and get a clear, plain-language explanation of exactly what it does.

Need a full AI spreadsheet workspace?

Frequently asked questions
Is the Excel Formula Generator free?

Can it fix a broken formula, not just generate one?
Yes — paste a formula returning an error like #N/A or #VALUE!, and it explains what's wrong and returns a corrected version.
What functions does it work best with?
Common, well-documented functions like SUM, VLOOKUP, XLOOKUP, IF, and the others listed below — it isn't limited to this list, but results are most reliable for these.
Is my formula or data stored?
