What is JSON to CSV Converter?
Paste a JSON array of flat objects and get a CSV file instantly — the column headers are the union of every object's keys, in first-seen order, and any object missing a key just gets an empty cell for it.
FAQ

A nested object or array value is stringified as-is into that cell rather than split into extra columns — CSV has no native way to represent nested structure.
