Frequently Asked Questions
Is my JSON data sent to a server?
No, all formatting and validation happens in your browser. Your data never leaves your device.
How large can the JSON file be?
There's no hard limit, but very large files (>10MB) might slow down your browser. For best performance, keep it under 5MB.
Can I copy the formatted result?
Yes, there's a copy button next to the output. You can also download it as a .json file.
