CSV vs TSV — what is the difference?

CSV (Comma-Separated Values) uses a comma as the column separator and wraps fields containing commas in double quotes. TSV (Tab-Separated Values) uses a tab character instead, which avoids the need to quote most fields since tabs rarely appear in data.

When to use TSV instead of CSV?

TSV is often simpler to parse because the tab delimiter almost never appears inside field values, eliminating the need for quoting rules. Many bioinformatics tools and spreadsheet applications accept TSV by default.
