Kept running into the same problem: messy CSVs with duplicate rows, stray whitespace, and broken email fields, and no fast way to clean them without spinning up a script every time.
So I built CSVCleaner (hackiom.xyz) — drop a file in and it removes duplicates, trims whitespace, and validates emails right in your browser. Nothing gets uploaded to a server, so it works fully offline and there’s zero signup friction.
Still actively building this out, so I’d love feedback on what other cleanup features would be useful — currently thinking about type detection, column renaming, and null handling next.
Happy to answer questions about how it works under the hood.
