Frequently Asked Questions

What JSON format is supported?

Your JSON must be an array of objects, like [{"key":"value"}]. Each object becomes a row, and keys become column headers.

Can I convert nested JSON?

This converter works best with flat JSON objects. Nested objects will have [object Object] placeholders. Consider flattening nested structures first.

How are special characters handled?

Values containing commas, quotes, or newlines are properly quoted and escaped in the CSV output.

Is my data stored or sent anywhere?

No. All conversion happens entirely in your browser. Nothing is sent to any server.
