CSV and TSV Converter

Convert CSV to tab-separated text, TSV to comma-separated text, or spreadsheet rows to a chosen delimiter.

Input
Delimited text or a supported local spreadsheet file and conversion direction.
Output
Normalized CSV or TSV text ready to copy or download.
Real limitations
Delimiter conversion does not infer schemas or preserve workbook styling, formulas, merged cells, or multiple sheets.
Privacy and data handling
delimited text or a supported local spreadsheet file and conversion direction is processed in this browser tab. Convertr does not receive or store it; closing or reloading the page clears the working state unless the tool explicitly offers a local download.

How to use this tool

  1. Provide delimited text or a supported local spreadsheet file and conversion direction in the tool controls.
  2. Choose the settings that affect normalized CSV or TSV text ready to copy or download, then run the tool.
  3. Review normalized CSV or TSV text ready to copy or download before copying or downloading it.

Common failure modes

Malformed quoting, inconsistent rows, unsupported workbook content, or binary data can prevent a reliable conversion.

Useful example

Convert a CSV row containing a comma inside quotes into TSV without losing the embedded comma.
