Frequently Asked Questions

Find Quick Answers

What JSON formats does this converter support?

The converter supports standard JSON formats including arrays of objects, nested objects, and simple key-value pairs. It automatically flattens nested structures for CSV output.

Can I convert large JSON files?

Yes, the tool can handle reasonably large JSON files, but very large files (over 10MB) may impact browser performance. All processing happens client-side for privacy.

What happens with nested JSON objects?

Nested objects are flattened using dot notation. For example, {"user": {"name": "John", "age": 30}} becomes columns: user.name, user.age.

Is my data secure?

Yes, all conversion happens entirely in your browser. No data is sent to any server, ensuring complete privacy and security.
