Frequently Asked Questions
What does this tool do?
It validates JSON syntax, formats it with proper indentation, and helps identify errors in your JSON data.

No, all processing happens locally in your browser. Your data never leaves your device.
Can I format large JSON files?
Yes, though very large files may take a moment to process depending on your device.
