How it works

1. Paste your CSV into the editor (delimiter is preset to Comma).
2. Confirm the output delimiter (preset to Tab).
3. Process and download the.tsv file.

Use cases

• Convert a comma CSV into a TSV for a tab-aware data tool.
• Move a CSV out of a spreadsheet and into a script that expects TSV.
• Re-encode a CSV as TSV when the data contains many commas inside fields.
• Prep a CSV for import into a tool that doesn't handle quoting well.

Frequently asked questions

What if my values contain tabs?

Handled automatically. Values containing a tab, quote, or newline are wrapped in quotes in the output so a strict TSV parser reads them correctly.

Is the header preserved?

Yes. The first row is kept exactly as-is at the top when the header option is ticked.

What's the difference vs just renaming the file?

Renaming doesn't replace the delimiter. This converter re-encodes the rows with tab separators and reapplies quoting where needed, so the output is a real TSV file.

Is there a size limit?

Up to 2 MB of input per job, comfortably tens of thousands of rows.
