Yes. The parser follows the standard CSV quoting rules: a field wrapped in double quotes can contain commas, semicolons, or line breaks, and a doubled quote ("") inside a quoted field is read as one literal quote character.
Comma, semicolon, tab, and pipe. Auto-detect looks at the first line of your file and picks the delimiter that shows up most, or you can force one from the dropdown if auto-detect guesses wrong on messy data.
An array of flat objects, like [{"name":"Ada","city":"London"}]. Column headers are built from every key that appears across the array, so it also works if some objects are missing a field.
