About the TSV to CSV Tool
TSV and CSV carry the same information with a different delimiter, but that difference matters to whichever program you are feeding. Tab-separated output is what you get when you copy from a spreadsheet or export from many scientific and bioinformatics tools; comma-separated is what most import interfaces expect.
Converting properly means more than swapping characters, because any value containing a comma must be quoted to avoid corrupting the row structure. This converter handles that escaping correctly and runs entirely in your browser.
How to Use TSV to CSV
- Paste your tab-separated data into the input area.
- Press Convert to translate the delimiters.
- Check that values containing commas have been quoted correctly.
- Copy or download the CSV output.
When to Use This Tool
- Converting data copied directly from a spreadsheet into proper CSV
- Preparing scientific tool output for a CSV-only import interface
- Standardising mixed-format data files into a single delimiter
- Making tab-delimited exports usable in tools that require CSV
- Cleaning up pasted table data for further processing
Things Worth Knowing
- Values containing commas are automatically wrapped in quotes to preserve field boundaries.
- Existing double quotes within values are escaped by doubling, per the CSV convention.
- Row structure and column order are preserved exactly.

Frequently Asked Questions
Why not just find-and-replace tabs with commas?
Because any value that already contains a comma would split into two fields, silently corrupting your data. Proper conversion quotes those values so field boundaries survive.
Which format is better?
TSV is simpler and less prone to delimiter collisions, since tabs rarely appear inside values. CSV is far more widely supported. Use whichever your destination tool expects.
Can I convert CSV back to TSV?
Yes โ the same tool handles the reverse direction.
What if my data contains actual tab characters inside a value?
That breaks TSV at the source, since the delimiter is ambiguous. Such values need quoting or cleaning in the original file before conversion.
