TSV to CSV Converter

TSV (tab-separated values) is common in database dumps, Excel copy-paste, and older ETL feeds. Many tools still expect CSV with commas. This free TSV to CSV converter splits on tabs (respecting quotes), then emits RFC 4180 CSV you can download or open in other converters on this site.

Key features

  • Quote-aware TSV parsing.
  • Client-side conversion with CSV download.

About the TSV to CSV format

Each line is a record; fields are separated by tab characters. Quoted fields may contain tabs. Conversion maps those fields into comma-separated cells with standard CSV escaping.

Common use cases

  • Opening a Postgres COPY ... WITH (FORMAT text) dump in Excel.
  • Converting a tab-delimited export from a CRM into CSV for import elsewhere.
  • Cleaning a paste from a spreadsheet that used tabs instead of commas.

How to use this tool

  1. Paste TSV or upload a .tsv file.
  2. Preview rows, then download CSV.

Example

Input TSV

name	city
Ada	London

Output CSV

name,city
Ada,London

Tips for best results

  • Keep a header row so column names survive the conversion.
  • Use CSV to TSV for the reverse direction.

Common pitfalls

Spaces that look like columns in a proportional font may not be tabs.

Mixed comma-and-tab files need cleanup before converting.

Frequently asked questions

Are tabs inside quoted fields preserved?

Yes. Quoted TSV fields are parsed like CSV quotes, then re-escaped for comma-separated output.
