FAQ
What JSON can this convert?
An array of objects. Each object becomes a row and the union of all keys becomes the header. Arrays of arrays are also supported, where the first array is the header.
Will commas or quotes in my data break it?
No. Fields containing commas, quotes or newlines are quoted and inner quotes are doubled, producing valid CSV for Excel, Google Sheets and most tools.
