Why Convert TSV to CSV?

TSV (tab-separated values) and CSV (comma-separated values) contain the same data — just with different delimiters. But CSV is far more widely supported. Most database import tools, CRMs, analytics platforms, and programming libraries expect CSV by default. If your data source exports TSV, converting to CSV ensures compatibility everywhere.

Conversion happens in your browser — no data is uploaded anywhere.

Proper Quoting Matters

A naive find-and-replace of tabs with commas breaks when cell values contain commas. The tool handles this correctly: fields containing commas, quotes, or newlines are automatically wrapped in quotes and properly escaped. This ensures the output is valid, parseable CSV.
