TSV ↔ CSV Converter
Convert between tab-separated and comma-separated values.
About TSV ↔ CSV Converter
Convert between TSV (Tab-Separated Values, exported from Excel by default) and CSV (Comma-Separated Values). Handles quoted fields, newlines in cells, and special characters. Works in both directions.
Use Cases
Converting Excel paste data to CSV format, preparing TSV exports for CSV-only importers, switching between database export formats, cleaning data from clipboard.
How It Works
Splits each line by the source delimiter, then re-joins with the target delimiter. Adds quotes around fields that contain the target delimiter or newlines.
Frequently Asked Questions
When I paste from Excel, what format do I get?
Copying cells from Excel and pasting gives TSV (tab-separated). Use this tool to convert it to CSV.
What if my data contains commas and I convert to CSV?
Fields containing commas are automatically wrapped in double quotes in the CSV output.
