Convert to CSV
The CSV output appears instantly. Invalid TSV is caught with a clear message pointing at the problem.

Why convert TSV to CSV?
The usual reason is spreadsheets, data exports and bulk imports, where a flat table is all you need. TSV is strong for data with lots of commas, but teams switch to CSV when they need its particular shape.
Is the data changed?
No. Both TSV and CSV represent the same kind of structure, so the conversion is a faithful re-expression — every value is preserved.
About TSV
TSV is CSV's cousin using tabs instead of commas, which avoids quoting problems when data itself contains commas. Best for data with lots of commas, and pasting between spreadsheets where tabs separate columns cleanly.
About CSV
CSV is the simplest tabular format, one row per line with comma-separated fields, readable by every spreadsheet and database. Best for spreadsheets, data exports and bulk imports, where a flat table is all you need.
Common Uses for TSV to CSV
- Migrating data from a system that exports TSV into one that only accepts CSV.
- Converting a TSV spreadsheet export into CSV so it drops straight into your spreadsheet or database.
- Preparing TSV data for a tool, language or teammate that works natively with CSV.
- Quickly inspecting TSV content in CSV form, which can be easier to read or diff.
- One-off conversions where installing a library or writing a script would be overkill — paste, convert, done.

Tips & Things to Know
The conversion runs entirely in your browser
Your TSV data is processed on your own device and never uploaded to a server. That makes it safe for internal, confidential or personal data — when you close the tab, nothing is left behind.
A faithful re-expression
Both TSV and CSV describe the same kind of structure, so the conversion preserves your data exactly — nothing is dropped or reshaped.
Validation catches mistakes early
If your TSV has a syntax error, the tool tells you what and where instead of producing broken CSV. Fixing the source and converting again takes seconds.
