About TSV to CSV
TSV to CSV converts tab-separated values into comma-separated values. Paste rows copied from a spreadsheet or a tab-delimited export and get CSV back, with a comma between each column and quotes added around any cell that contains a comma, a quote, or a line break so the file stays valid. It is handy when a tool or import expects CSV but your data arrived separated by tabs.
The conversion runs entirely in your browser, so the text you paste is turned into CSV 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 do I need an account?
- Yes, it is completely free, with no account and no sign-up. There are no usage limits and nothing to install. Paste your TSV and copy the CSV it produces.
- Is my data uploaded anywhere?
- No. The conversion happens locally in your browser, so the tab-separated data you paste never leaves your device. Nothing is sent to a server or stored.
- How do I use it?
- Copy your tab-separated rows, for example straight from a spreadsheet, and paste them into the box. The tool splits each line on the tab characters and joins the cells with commas, then you copy the CSV result.
- What happens to cells that contain a comma?
- They are wrapped in double quotes so the comma stays inside the cell instead of splitting it into two columns. Cells that contain quotes or line breaks are quoted the same way, which is standard CSV behaviour.
- Does it detect a header row?
- No. Every line is treated the same way, so the first row is converted just like the rest. The tool also expects real tab characters between columns, so data separated by spaces will not be split.
