How to use the TSV to CSV Converter

  1. Paste tab-separated data — copying a range straight out of a spreadsheet gives you TSV.
  2. Choose the output delimiter.
  3. Copy or download the CSV.

Example

Input
name	role
Ada	Mathematician, writer
Output
name,role
Ada,"Mathematician, writer"

Common use cases

  • Converting a copied spreadsheet selection into a CSV file.
  • Preparing data for a tool that only accepts comma-separated input.
  • Fixing an export that used tabs when the importer expects commas.

Limitations and things to watch for

  • Fields that contain the output delimiter, a double quote or a line break are wrapped in quotes and internal quotes are doubled, following RFC 4180.
  • Empty trailing columns are preserved so the column count stays consistent across rows.

Frequently asked questions

Why does the output have quotes that my input did not?
Because a field contained a comma, a quote or a line break. Quoting is required for the file to be read back correctly, and any spreadsheet will strip the quotes when it opens the file.
Can I paste directly from Excel or Google Sheets?
Yes. Copying a range from a spreadsheet puts tab-separated text on the clipboard, which is exactly what this tool expects.
