Why switch delimiters

CSV breaks when your data itself contains commas, which is common in addresses and descriptions. TSV uses tabs instead, so commas inside fields need no special treatment and the file stays readable.

Some tools and locales prefer one over the other: Excel in certain regions expects semicolons or tabs, while most web APIs speak comma CSV.

Safe conversion

The converter parses quoted fields properly before re-joining with the new delimiter, so a comma inside quotes never splits a column by mistake. Fields that need quoting in the target format are quoted automatically.

Format detection looks at the first line: more tabs than commas means TSV, otherwise CSV.

CSV TSV Converter FAQs

How does it detect CSV vs TSV?
It counts tabs and commas in the first line. More tabs means TSV; otherwise it assumes CSV. Ambiguous single-column data defaults to CSV.
Will commas inside fields break the conversion?
No. Quoted fields are parsed first, so commas inside quotes stay inside their cell and are re-quoted if needed in the output.
What about tabs inside TSV fields?
Fields containing tabs are wrapped in quotes during parsing, and the quotes are preserved or re-applied in the output.
Does it handle quoted line breaks?
Yes. A line break inside a quoted field is treated as part of the cell, not as a new row.
Is my data uploaded anywhere?
No. The whole conversion runs in your browser, so your datasets never leave your device.
