Can I Spreadsheet?

Spreadsheet Migration Audit

Drop in an .xlsx and see which of your formulas break — or silently change behavior — in the app you're moving to. Verdicts are matched against our compatibility dataset: LibreOffice results come from actually executing formulas in real LibreOffice builds; Excel and Google Sheets verdicts are documentation-based.

What this is (and isn't): function-level triage from a pre-computed compatibility dataset — LibreOffice verdicts from formulas we executed in real LibreOffice builds, Excel and Google Sheets verdicts from official documentation. It flags functions known to be missing or to behave differently; it does not recalculate your workbook in the target app, so it cannot promise your specific numbers survive. Use it to know where to look first. How we verify.
