What is CSV ⇄ TSV?
Convert CSV to TSV or back with correct handling of quoted cells, embedded commas and escaped quotes — the edge cases naive find-and-replace breaks on. TSV pastes cleanly into Excel and Google Sheets and is friendlier for awk/cut pipelines.

- Paste your CSV or TSV into the input box or click “Load sample” to try it.
- Adjust the options in the toolbar if needed (delimiter, table name, format …).
- Click the convert button — the converted data appears instantly in the output pane.
- Copy the result with one click or download it as a file.
