What's the difference between formatting and validating JSON?

Formatting makes JSON more readable by adding proper indentation and line breaks. Validation checks if the JSON syntax is correct and follows the JSON specification. Our tool does both automatically.

Can this tool handle large JSON files?

Yes, our tool can handle JSON files up to several megabytes in size. For extremely large files (100MB+), performance may vary depending on your browser and device.

Is my JSON data safe?

Absolutely! All JSON formatting and validation happens entirely in your browser. Your data never leaves your device or gets sent to our servers.
