Does it support CSV without a header row?

Yes. Select "No header row" to output each row as an array instead of an object.

Are quoted values with commas handled correctly?

Yes. The parser handles RFC 4180 quoting, including fields that contain commas or newlines.

Does it handle large files?

All processing is done in-browser. For very large files (tens of thousands of rows), processing may be slow.
