Built by one developer who hates broken imports

Hi, I'm Anas, a developer from the Netherlands. I built SheetFix because cleaning a spreadsheet before an import shouldn't take an afternoon — and you shouldn't have to upload customer data to a stranger's server to do it.

SheetFix processes your files in your own browser. Every fix is shown before it's applied and can be undone. Where a value is ambiguous, like 03/04/2025, SheetFix flags it instead of guessing.

SheetFix is new and actively developed. If something doesn't work or you're missing a feature, tell me — I read every message.
