Questions and answers
Is the conversion private?
Yes. The conversion runs in your browser and the file is never uploaded.
Which CSV formats work?
Standard RFC 4180 CSV with a header row: quoted fields, doubled quotes inside quotes, line breaks inside quotes, a UTF-8 byte-order mark, and comma, semicolon or tab delimiters (detected from the header line).
What happens to values that do not fit the detected type?
Types are only assigned when every sampled value fits, so values normally convert cleanly. If a later row does not fit, it is kept as text rather than dropped.
