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.
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.
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.
Converting CSV to TSV takes three steps:
Paste or upload your CSV: Enter data or drag and drop a .csv file. Input delimiter and first row as header are auto-detected.
Set options: Choose whether to strip surrounding quotes. Optionally set output delimiter (tab, pipe, semicolon, colon). Use reverse mode if you need TSV to CSV instead.
Convert and download: Click Convert. Preview shows TSV (tabs as \t if enabled). Download the .tsv file or copy the result.
CSV uses comma (or other character) as delimiter; TSV uses tab. TSV is common in bioinformatics and some legacy systems. This tool converts between them; the same page also does TSV to CSV.
Yes. Quoted fields and multi-line quoted values are handled correctly so commas inside quotes don't break columns.
When processing is client-side, your files stay on your device and are not uploaded to our servers for conversion.
Yes. Use the reverse mode (TSV to CSV) on the same page to convert tab-separated data to comma-separated.
Yes. Output delimiter can be tab, pipe, semicolon, or colon.
Highlights:
Typical situations:
Simple find-replace from comma to tab can break quoted fields. Our converter parses CSV correctly and outputs valid TSV. Reverse mode (TSV to CSV) on the same page gives you both directions with minimal extra development.
Before you convert:

CSV uses comma as delimiter; TSV uses tab. This tool converts both ways (CSV to TSV and TSV to CSV on the same page).
Yes. Quoted fields are handled correctly.
Many Asli Tools converters run client-side; when that applies, your file is processed locally in your browser.
Modern phones, tablets, and desktops with an up-to-date browser work well.
Yes. Use reverse mode for TSV to CSV.
If the tool supports batch mode, use it after reading any on-page limits for file count and size.
Limits depend on the tool and your device memory; check the upload hint on the tool page.
