Frequently Asked Questions

What JSON formats are supported?

Any valid JSON — objects, arrays, nested structures, strings, numbers, booleans, and null values. The tool will report errors for invalid JSON.

Is my data safe?

Can I format large JSON files?

The tool handles large JSON payloads efficiently in-browser. For extremely large files (10MB+), performance may vary based on your device.
