help FAQ

What is the difference between TSV and CSV?

TSV uses a tab character (\t) as the separator instead of a comma. This avoids issues when data fields contain commas, such as in address fields or text descriptions.

Which tools accept TSV?

Most databases (MySQL, PostgreSQL), bioinformatics tools (BLAST, Galaxy), and data analysis platforms (R, Python pandas) natively support TSV files.

Can I open a TSV in Excel?

Yes. Rename the file to .txt and use Excel's import wizard, or simply open it: Excel detects tab delimiters automatically in most versions.
