Frequently Asked Questions

What is JSON formatting and why is it important?
JSON formatting makes your JSON data human-readable by adding proper indentation, line breaks, and spacing. This improves debugging, code reviews, and data analysis.
Can this tool validate invalid JSON?
Yes, our JSON formatter will detect and highlight syntax errors in invalid JSON, helping you identify missing commas, brackets, or quotes that need to be fixed.
Is my JSON data secure when using this tool?
Absolutely! All JSON processing happens locally in your browser. No data is sent to our servers, ensuring your sensitive information remains private.
