FAQ
03
What JSON shape is expected?
An array of flat objects. Each object becomes a row and the union of keys becomes the header.
Are commas and quotes handled in CSV?
Yes. Cells with commas, line breaks, or quotes are wrapped in double quotes with standard escaping.
Does it send my data anywhere?
No. Parsing and serialization run in this tab.
