How to convert TSV to CSV
- Add your .TSV file - drop it in the box above or click to browse.
- Convert it to .CSV in a few seconds.
- Download your new .CSV file.
What to expect
- Values containing commas must be wrapped in double quotes to produce valid CSV - spreadsheet apps do this automatically, but a raw tab-to-comma text-replace does not.
- All data is preserved; this is a delimiter swap with no data loss - every row, column, and value transfers intact.
- If the
.tsvwas saved in a non-UTF-8 encoding, set the character set in the import dialog to prevent accented or non-Latin characters from appearing corrupted.
Frequently asked questions
Does converting TSV to CSV lose any data?
No. Both formats store the same plain-text table and only the delimiter changes, so all values, row order, and column order remain identical.
My values contain commas - will the CSV still be valid?
Yes, if you use a spreadsheet. Excel, LibreOffice Calc, and Google Sheets automatically wrap those values in double quotes. A raw text-replace command will not add quoting and may produce a broken file.
My file has a `.tab` extension, not `.tsv` - does that change anything?
No.
.tab is the same tab-delimited format and every method above applies identically.Can I convert multiple TSV files to CSV at once?
Yes - on the command line, loop over files using
tr or a Python script; LibreOffice also supports batch conversion via macros.
