How to use it

  1. Paste comma-separated data or choose a UTF-8 CSV file.
  2. Choose the changes you want to apply.
  3. Review the preview and download the complete cleaned CSV.

Good to know

Quoted commas, embedded newlines, and UTF-8 are supported. Rows with a different number of columns are rejected. The preview shows the first 20 data rows.

Formula protection prefixes an apostrophe to cells that could execute in spreadsheet software. It changes those values intentionally. Keep it enabled for untrusted data.
