TSV to CSV Converter
Paste tab-separated data (TSV) and get clean, properly escaped CSV output in real time. The conversion happens live as you type or paste — no button click needed. Tabs become commas, and any field that contains a comma, double quote, or newline is automatically wrapped in quotes with internal quotes doubled per the CSV specification (RFC 4180).
A preview table shows the parsed data so you can verify the structure before exporting. Row and column counts are displayed to help you spot truncation or parsing issues quickly.
Copy the CSV to your clipboard or download it as a .csv file. Everything runs in your browser — no data is uploaded, no account is needed, and the tool works offline.

Frequently asked questions
Does it handle quoted fields in the TSV input?▼
The tool splits each line on tab characters. If your TSV fields themselves contain tabs that are escaped or quoted, the tool treats each literal tab as a field separator. Standard TSV does not define a quoting mechanism, so this behavior matches the format specification.
What if my data has commas inside fields?▼
The tool automatically wraps any field containing a comma in double quotes in the CSV output, so commas inside your data are preserved correctly and won't be misinterpreted as field separators by CSV readers.
Is the conversion instant?▼
Yes. The TSV is converted to CSV in real time using React's useMemo hook. As soon as you paste or edit the input, the output updates without clicking a button.
Can I convert CSV back to TSV?▼
This tool is one-directional: TSV to CSV. For the reverse conversion, look for a dedicated CSV to TSV tool or swap commas for tabs in a text editor.
