❓ Frequently Asked Questions
Everything you need to know about JSON formatting
What is JSON formatting?
JSON formatting (or "pretty printing") adds proper indentation, line breaks, and spacing to JSON data to make it more readable. It transforms compact JSON into a structured, easy-to-read format without changing the data itself.
Is my JSON data secure?
Yes! All JSON processing happens entirely in your browser. Your data is never sent to our servers or stored anywhere. The tool works completely offline once loaded, ensuring your sensitive data remains private.
What's the difference between formatting and minifying?
Formatting adds indentation and line breaks to make JSON readable by humans.
Minifying removes all unnecessary whitespace to reduce file size, making it ideal for production use where bandwidth matters.
Can this tool handle large JSON files?
Yes, the tool can handle reasonably large JSON files. However, very large files (several MB) might slow down your browser. For extremely large files, consider using command-line tools or server-side processing.
What happens if my JSON has syntax errors?
The validator will detect syntax errors and show you exactly where the problem is, including the line number and a description of the error. This helps you quickly identify and fix issues in your JSON data.
