Frequently Asked Questions
What is a TSV file?
TSV (Tab-Separated Values) is like CSV but uses a tab character as the delimiter instead of a comma. It's commonly used when data contains commas.
Will quoted fields be handled correctly?
Yes. The tool correctly handles RFC 4180-style quoting so fields containing the delimiter character remain intact.
What file extension should I use for tab-delimited files?
.tsv is standard for tab-separated files, though .txt is also commonly used.
Can I convert from semicolon to comma (European CSV to standard CSV)?
Yes — just select Semicolon as the input delimiter and Comma as the output delimiter.
