FAQ

Does CSV to JSON preserve data types?

The converter uses dynamic typing, so common numbers and booleans can become JSON values instead of strings.

Can it handle quoted commas?

Yes. Papa Parse handles quoted CSV fields, escaped quotes, and common delimiters more reliably than a hand-written parser.
