About CSV to TSV

CSV to TSV converts comma-separated values into tab-separated values. Paste your CSV and get back rows with a tab between each column, ready to paste straight into a spreadsheet or a tool that expects tabs. It correctly parses quoted CSV fields, so a comma inside a quoted value stays part of that cell instead of starting a new column.

The conversion runs entirely in your browser, so the CSV you paste is turned into TSV on your own device and nothing is uploaded to a server. It is free, needs no account or sign-up, has no usage limits, and there is nothing to install.

Frequently asked questions

Is it free, and is there a sign-up?
Yes, it is free to use, with no account and no sign-up. There are no usage limits and nothing to install. Paste your CSV and copy the TSV it gives you.
Does my CSV get uploaded to a server?
No. Everything happens in your browser, so the data you paste stays on your own device. Nothing is sent anywhere or saved.
How do I use it?
Paste your comma-separated rows into the box. The tool reads the CSV, including quoted fields, and rebuilds each row with tab characters between the columns for you to copy.
Why would I want tab-separated output?
Tabs are convenient when you paste directly into a spreadsheet, since each column drops into its own cell. Some import tools and scripts also prefer tabs because values rarely contain a tab, unlike commas.
What if a cell contains a tab or a line break?
TSV has no way to quote a cell, so any tab or line break inside a value is replaced with a single space to keep the columns lined up. If your data relies on those characters staying intact, CSV is the safer format to keep.
