frequently asked questions
does it detect the delimiter?
yes. it picks comma, semicolon or tab based on the first line, and handles quoted fields with embedded delimiters and newlines.
are numbers converted?
by default numeric and true/false values are typed. choose all strings to keep every value as text, or array of arrays to skip headers.
is my csv uploaded?
no, parsing runs locally in your browser.
