Which delimiters are supported?

Comma, semicolon, tab and pipe are detected automatically; quoted fields and doubled quotes follow RFC 4180. Numbers and true/false are typed.

Is my file uploaded to a server?

No. This tool runs entirely in your browser. You can open your browser's network tab and verify no request carries your file.
