# CSV to TSV Converter

Paste a CSV and download a clean tab-separated TSV file.

Convert CSV to TSV (tab-separated values) in one click. Quoting is removed where possible and reapplied where needed for fields containing tabs, quotes, or newlines. Header row is preserved.

- **Category:** Text
- **Availability:** Free to use without an account, email address, subscription, or payment.
- **Input:** Entered in the browser

## 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.
