How It Works
Supported Structures
We automatically detect whether your JSON is a single object or an array of objects.
Keys are converted into the CSV headers, and values are mapped to the corresponding
columns.
Nested Objects & Arrays
Deeply nested JSON objects and arrays will be Stringified (converted to text
representation like
[object Object] or literal JSON) for safety. To
maintain a flat CSV, ensure your JSON is relatively flat.

Frequently Asked Questions
