FAQ
How do I convert CSV to TSV online for free?
Paste your delimited text and choose the target separator — the tool auto-detects the source delimiter and rewrites each row in your browser, with no upload, requoting any field that would collide with the new separator.
Why does requoting matter?
If a field contains the new delimiter, it must be quoted or the row would split incorrectly. The tool wraps such fields in quotes automatically, so the converted output parses cleanly.
Is my data uploaded?
No. Conversion runs locally and nothing is stored; it works offline.
Which delimiters are supported?
Comma, tab, semicolon and pipe, in any direction. The source is auto-detected from the text; the target you choose.
Limits
Auto-detects the source from the content. Fields with embedded newlines are preserved via quoting.
