How to Convert TSV to CSV Online
Paste tab-separated values (TSV) — for example, data copied from a spreadsheet — into the box above and it converts to comma-separated values (CSV) instantly. Any field that itself contains a comma, double quote, or line break is automatically wrapped in quotes (with internal quotes doubled) so the output stays valid CSV.
Example
The TSV row Jane 28 Boston, MA converts to Jane,28,"Boston, MA" — the comma inside "Boston, MA" is preserved correctly because the field is quoted.
Common Use Cases
- Converting data copied from Excel or Google Sheets (which pastes as TSV) into CSV format.
- Preparing TSV exports for tools or scripts that only accept CSV input.
- Reformatting tab-delimited log or export files for spreadsheet or database import.
FAQs
What happens if a cell already contains a comma?
The tool wraps that field in double quotes automatically, so the comma is treated as part of the value rather than a new column separator in the resulting CSV.
Does this handle quotes inside a cell?
Yes — any double quote character inside a field is escaped by doubling it (per the CSV standard), and the field is wrapped in quotes.
Can I paste data copied directly from a spreadsheet?
Yes — Excel and Google Sheets both copy selected cells as tab-separated values by default, so you can paste directly into the input box above without reformatting anything first.
