TSV to CSV Converter
Convert tab-separated (TSV) data to comma-separated (CSV).
Tabs to commas
TSV files separate fields with tabs instead of commas, a common format especially for data copied from spreadsheets. This converts TSV to CSV, in your browser, so tab-separated data becomes the more widely-expected comma-separated form.
Load your TSV data to convert it to CSV.
Why TSV and CSV coexist
Both formats do the same job of storing tabular data as text, and they persist side by side for practical reasons. TSV has one real advantage: since data rarely contains tab characters, tabs are a clean separator that avoids the classic CSV headache of commas appearing inside field values, which need special handling. This is why copying from a spreadsheet often gives tab-separated data. But CSV is the more universally expected format, so converting TSV to CSV is frequently needed to feed data into a tool or system that assumes commas. A good conversion handles the switch properly, including quoting any fields that now contain commas so they are not mistaken for separators — exactly the complication TSV avoided. Doing it in the browser keeps the data local and private, so even sensitive tabular data is converted on your own device without being uploaded to an online converter.
Common questions
Why does TSV exist alongside CSV?
Tabs are a clean separator since data rarely contains them, avoiding the CSV headache of commas inside field values — which is why copying from spreadsheets often gives TSV.
What does the conversion handle?
Switching tabs to commas, and quoting any fields that now contain commas so they are not mistaken for separators.
Is my data uploaded?
No. The conversion happens in your browser, so the data stays on your device.
