Questions answered

Frequently asked questions

Everything you might be wondering about the JSON to CSV Converter.

What JSON format is expected?
An array of flat objects, e.g. [{"name":"A","age":1}, {"name":"B","age":2}] — the tool collects all unique keys across objects as CSV columns.
What happens with nested objects or arrays?
Nested values are converted to their JSON string representation inside the CSV cell, since CSV itself has no concept of nesting.
Is it free and private?
Yes — free, no sign-up, and everything runs in your browser.
