Convert CSV to TSV, free in your browser

Convert comma-separated rows to tab-separated values while preserving cell order and text. Delimited content is parsed locally and safely quoted for the new separator.

How to convert CSV to TSV

1. Choose a CSV or TSV file.
2. Convert the rows to tab-separated values.
3. Preview and download the TSV file.

Limits & good to know

• CSV files up to 50 MB are processed on your device.
• Formula-like values receive a leading apostrophe to reduce spreadsheet formula injection risk.
• Malformed or ambiguous quoting may be interpreted according to the app’s CSV parser.

Frequently asked questions

Are my files uploaded to a server?

Your files are processed on your device, not uploaded to our servers. Your file and edits are saved in this browser for recovery, and previous documents remain in Saved drafts when you open another file. Use Saved drafts to resume or delete individual copies, or clear this site’s browser data to remove all copies. Browser storage can be cleared or become unavailable; download important work.

Will commas inside quoted values break the TSV?

No. Quoted values are parsed as cells before the delimiter changes.

Is this really free, or free "until you hit a limit"?

Really free. Unlike most "free" PDF sites there is no task-per-day cap, no locked Pro features, no watermark stamped on your file, and no payment step before download. Every tool is the full tool.
