What is the difference between CSV and TSV?

CSV uses commas to separate values while TSV uses tab characters. TSV avoids problems when data itself contains commas.

Can I convert TSV back to CSV?

Yes. Use our TSV to CSV converter to switch back to comma-separated format at any time.

Are headers preserved during conversion?

Yes. The first row is treated as headers by default and is preserved exactly as-is in the TSV output.
