Frequently Asked Questions

Is my JSON data secure when using this editor?

Yes, absolutely! All JSON editing and processing happens entirely in your browser. Your data never leaves your device and is not sent to any servers, ensuring complete privacy and security.

Can I edit large JSON files?

Yes, our editor can handle large JSON files efficiently. However, for very large files (several MB), you may experience slower performance depending on your device's capabilities.

What happens if my JSON has syntax errors?

Our editor provides real-time validation and will highlight syntax errors with detailed error messages and line numbers, making it easy to identify and fix issues in your JSON data.

Can I format minified JSON automatically?

Yes! Our editor includes auto-formatting features that will automatically indent and structure your JSON for better readability, even if it starts as minified or poorly formatted.

Does the editor support JSON comments?

Standard JSON doesn't support comments, and our editor follows the official JSON specification. However, you can use our editor to work with JSON-like formats that support comments, though validation may show warnings.
