How It Works

Upload or paste CSV, pick cleaning options, generate cleaned output, preview rows, then download CSV.

Common Fixes

Trim spaces, normalize header names, and remove empty rows that usually break imports.

FAQ

Can it handle quoted CSV values?

Yes. The parser handles quoted values, commas inside quotes, and escaped double quotes.

Will this upload my CSV to your server?

No. CSV processing is done in the browser for this tool flow.

What does header normalization do?

It converts headers to lowercase snake_case and removes unsupported symbols to improve import compatibility.
