Frequently asked questions
Which delimiters are supported?
Comma, semicolon and tab. Auto-detect picks the most likely delimiter from the first line, or you can choose it manually.
How are quoted fields handled?
Fields containing quotes, delimiters or line breaks are parsed and escaped according to RFC 4180, so commas inside quoted text don't break columns.
Is my data uploaded anywhere?
No, conversion runs entirely in your browser — safe for internal data.
