About TSV to CSV
- What does TSV to CSV do?
- Convert tab-separated data to comma-separated, quoting what needs it.
- Who is it for?
- Analysts and operations teams moving data between systems, developers who need a quick format conversion, and anyone whose CSV keeps breaking when Excel opens it.
- Is it free?
- Yes. TSV to CSV is free with no account, no watermark on your output, no daily cap and no trial period. Because it runs on your own device it costs us nothing to run, which is why there is no catch.
- Is it safe to use with confidential files?
- Yes, and not because we promise to behave. TSV to CSV never sends your file anywhere — the work happens in your browser. There is no upload, so there is no copy of your document in our systems at any point.
- What file formats are supported?
- Input: TSV, TXT, CSV. Output: CSV.
