FAQ
Q: How are nested objects handled?
Nested fields are flattened into columns as parent.child, and array fields are kept as JSON strings in cells.
Q: Will the file be uploaded to a server?
No. JSON to CSV runs entirely in your browser; the file never leaves your device.
Q: What if the CSV looks garbled?
The output includes a UTF-8 BOM, so Excel opens it without mojibake by default.
