Frequently asked questions

How are field names chosen?

With Use first row as headers enabled, cells from row one become JSON keys.

Are quoted commas supported?

Yes. Commas and newlines inside quoted CSV cells stay within that value.

What happens when rows have different lengths?

Missing cells become empty strings; extra cells are ignored when headers are enabled.

Can I use tabs or semicolons?

Yes. Choose comma, semicolon, or tab as the delimiter.

Does conversion upload my data?

No. CSV parsing and JSON generation run in your browser.
