Convert CSV to TSV (tab-separated values) instantly. Handles quoted fields and commas in values. Reverse mode: TSV to CSV on the same page. For bioinformatics and legacy systems. No signup, in your browser.

Need tab-separated output for bioinformatics tools, legacy databases, or systems that require TSV? Our CSV to TSV converter turns comma-separated (or other delimiter) data into tab-separated values. Quoted fields and values containing commas stay correct. We also offer the reverse on the same page: TSV to CSV—so one tool covers both directions and doubles your keyword reach. Preview shows input CSV structure and output TSV; you can show tab characters as \t in the preview.

What is CSV to TSV Conversion?

CSV to TSV conversion changes the column delimiter from comma (or semicolon, etc.) to tab. Input is comma-separated (or custom delimiter); output is tab-separated. Many bioinformatics tools and legacy systems expect tab-delimited files. Values that contain commas must be quoted in CSV; the converter handles quoted fields and multi-line quoted values correctly.

Why Choose Our CSV to TSV Converter?

We handle quoted fields correctly—values with commas inside quotes stay intact. You can optionally strip surrounding quotes from values. Preview shows both input CSV and output TSV structure; you can show invisible tab characters as \t. Download as .tsv with correct MIME type. Reverse mode (TSV to CSV) is on the same page: switch to convert TSV to CSV when needed. Optional custom output delimiter: tab, pipe, semicolon, or colon. All in your browser, free and private.
