About TSV to CSV

Convert Tab-Separated Values (TSV) files to Comma-Separated Values (CSV) format instantly. Free online TSV to CSV converter that preserves data integrity, handles large files efficiently, and works entirely in your browser without uploading data to servers.

Most spreadsheet and BI tools accept CSV as their default import format but choke on raw tab delimiters, so a TSV dump from a database export or a genomic pipeline often needs a quick delimiter swap before it's usable.

This tool re-parses the file on tab boundaries and re-emits it as comma-delimited, wrapping any field that already contains a comma in quotes so no data shifts columns.

It's a one-way fix aimed at getting command-line and lab-tool output into CSV-only software.

Category: Conversion & Export

Common Use Cases

  • Importing a database TSV dump into Google Sheets or Excel
  • Converting bioinformatics/genomic TSV output for CSV-only analysis tools
  • Cleaning up Linux command-line exports before sharing with non-technical teammates

Key Features

  • Re-quotes fields that contain commas after the delimiter swap, preventing column shift
  • Preserves UTF-8 encoding for scientific and international data
  • Handles large database/log exports without a size cap
  • Runs entirely in-browser, no upload

The TSV to CSV tool is compatible with: Database Exports, Linux Logs, Genomic Data.

If the resulting CSV still has ragged rows or stray whitespace from the original export, run it through Cleaning next before importing it into a spreadsheet.

Frequently Asked Questions

Why would a file be TSV instead of CSV in the first place?

Tab-separated exports are common from database dumps, Linux command-line tools, and bioinformatics or genomic data pipelines.

Does converting the delimiter risk breaking values that contain commas?

No, the converter properly quotes any field containing a comma when it switches to comma delimiters.

Useful for data engineers and bioinformaticians whose tools default to tab delimiters but whose downstream software expects CSV.
