About the CSV to TSV Converter
This CSV to TSV converter turns comma-separated data into tab-separated values that paste cleanly into spreadsheets and text editors. It uses a proper RFC 4180 parser, so quoted fields containing commas, quotes or line breaks are read correctly rather than being split in the wrong places.
Pick the delimiter your source actually uses — comma, semicolon or pipe — and the tool re-emits the rows with tab separators. Because TSV has no quoting convention, any tabs or newlines that were inside a field are safely replaced with spaces so every row keeps the right number of columns.
You get a live row and column count, and can copy the result or download it as a .tsv file. Everything happens locally in your browser, so confidential exports never leave your device.

Frequently Asked Questions
Why convert CSV to TSV at all?
Tab-separated values paste directly into Excel and Google Sheets without a text-import wizard, and they avoid ambiguity when your data itself contains commas. TSV is also the format you get when copying spreadsheet cells, so it round-trips naturally.
How are quoted fields with commas handled?
Correctly. The parser follows RFC 4180, so a field like "Khan, Ali" is treated as one value, not two. Escaped double quotes ("") inside quoted fields are also decoded properly.
What happens to tabs already inside my data?
Because TSV can't quote fields, any tab or newline characters found inside a value are replaced with a single space during conversion. This guarantees each output row has a consistent column count.
Is there a row limit?
There's no fixed limit — conversion runs in your browser, so the practical ceiling is your device's memory. Files with tens of thousands of rows convert in a fraction of a second.
