JSON to CSV Converter

JSON array input Convert to CSV

Frequently asked questions

What JSON structure does it accept?

It expects an array of flat objects, for example a list of records where each record has fields like name and age. The converter collects all keys across the records and uses them as the CSV header row.

What happens if some objects are missing keys?

Those cells are simply left empty in the CSV, so records with different shapes still line up under the shared header.

How are commas and quotes in values handled?

Values containing commas, quotes or newlines are wrapped in double quotes and inner quotes are doubled, following the standard CSV escaping rules.

Can it convert nested objects?

No. Nested objects and arrays are not flattened, so flatten your JSON first if you need a tidy spreadsheet.
