JSON to CSV — Frequently Asked Questions

How does this JSON to CSV converter handle nested objects?

Nested objects are flattened with dot notation so values like user.name become CSV columns. Arrays can be represented as joined values or serialized strings depending on the structure.

Is this JSON to CSV converter private?

Yes. The JSON to CSV converter processes input locally in your browser, so private data exports and API responses do not leave your device.
