What this tool does

Different tools export CSV with different separators, comma for most spreadsheets, semicolon for many European locales, tab for TSV, pipe for some database exports, and mismatching the one your next tool expects breaks the import. This tool parses the source with one delimiter, respecting quoted fields so a comma inside a quoted value is not mistaken for a column break, and re-serializes every row with the target delimiter, re-quoting fields that need it.

How to use it

  1. Paste your delimited data, or load the example.
  2. Pick the delimiter it currently uses, and the delimiter you want.
  3. Copy the converted result.

Privacy

This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.

Frequently asked questions

Is my CSV data uploaded anywhere?
No. Parsing and conversion happen in JavaScript running in the page, so spreadsheet exports never leave your device.
What happens to fields that contain the new delimiter?
They are wrapped in quotes automatically, the same way a normal CSV writer would, so the round trip stays valid.
Does the header row need special handling?
No, every row is converted the same way, so a header row carries over exactly like any other row.
