CSV to TSV Converter

About this tool

Convert between comma-separated (CSV) and tab-separated (TSV) data. Handy when moving data between tools that prefer one delimiter.

Example

Input: name,age

Output: name<TAB>age

Privacy

This tool runs entirely in your browser. Your data is processed locally and never uploaded to a server.

How to use this tool

1. Paste your CSV or TSV data into the input box.
2. Choose the direction you want, CSV to TSV or TSV to CSV.
3. Check the preview or output area to confirm the delimiter changed correctly.
4. Copy the converted text and paste it into your spreadsheet, editor, or import tool.

Step by step, what happens

1. The tool reads each line as one row and looks for the current delimiter between fields.
2. It rewrites the same rows using the target delimiter, switching commas to tabs or tabs to commas.
3. It keeps the row structure intact so the data stays in the same order.
4. You can then copy the converted result and use it in another tool that expects that format.

Worked example

Suppose you have a small CSV list of users and need to paste it into a tool that expects TSV.

Input: name,role Ava,admin Ben,editor

1. Paste the CSV text into the converter.
2. Select CSV to TSV so commas become tab characters.
3. The tool outputs the same rows with tab-separated fields.

Tips and common mistakes

• Make sure the input uses the correct delimiter for the direction you choose, otherwise the fields may not split as expected.
• If your data contains commas inside quoted values, check that the source CSV is well formed before converting it.
• Use plain text only, since spreadsheet formatting and cell colors are not preserved in a delimiter converter.
• If a row looks wrong after conversion, verify that every line has the same number of fields.
