Frequently Asked Questions
Q:
What if my JSON has syntax errors?
The tool will highlight the error and show you exactly what's wrong, making it easy to fix syntax issues.
Q:
Can I format large JSON files?
Yes! The tool can handle large JSON files efficiently. However, for extremely large files (>10MB), performance may vary.
Q:
Is my JSON data secure?
Absolutely! All formatting is done locally in your browser. No data is sent to any server or stored anywhere.
