Source format

TSV

TSV (Tab-Separated Values) is similar to CSV but uses tabs as delimiters, commonly used in bioinformatics, data exports, and systems where fields may contain commas.

Target format

CSV

CSV (Comma-Separated Values) is the most universal data format — readable by Excel, Google Sheets, databases, and virtually every programming language.

How it works

  1. 1. Click the button above to open Reparatio. Click Upload File and select your TSV file.
  2. 2. Reparatio previews your data instantly — schema, column types, and the first rows — so you can confirm the file loaded correctly.
  3. 3. Select CSV from the format dropdown and click Download Converted File. Done.

Common questions

Is it free?

Up to 100 rows are always free with no account required. Register a free account and verify your email to get 250 rows and 25 conversions per day. Full files require a Standard ($29/mo) or Professional ($79/mo) plan.

Is my data safe?

Files are processed in memory and never stored. They are not used for any purpose other than your conversion. See the Privacy Policy.

What's the file size limit?

Free accounts: 10 MB. Standard plan: 500 MB. Professional plan: 2 GB.

Can I automate this?

Yes — Reparatio has a REST API, CLI, Python/JS SDK, and an MCP server for AI assistants. All are available on the Professional plan ($79/mo). See the API docs.
