Frequently Asked Questions
What is JSON formatting?
JSON formatting (also called beautifying or pretty printing) adds proper indentation, line breaks, and spacing to compressed JSON data, making it much easier to read and understand while maintaining the exact same data structure.
Is this JSON formatter free to use?
Yes! Our JSON formatter is completely free with no limitations on file size, number of conversions, or features. No registration or payment required.
Does it validate JSON syntax?
Absolutely. The tool automatically validates your JSON syntax as you format or minify. If there are any syntax errors, it will display a clear error message showing exactly what's wrong.
What's the difference between format and minify?
Format (beautify) adds spacing, indentation, and line breaks to make JSON human-readable. Minify does the opposite - it removes all unnecessary whitespace to create the smallest possible file size, ideal for production use.
Is my data secure and private?
Yes, completely secure. All JSON processing happens entirely in your web browser using JavaScript. Your data is never uploaded to our servers or transmitted anywhere.
Can I format large JSON files?
Yes! There are no file size restrictions. However, very large files (multiple MB) may take a moment to process depending on your device's performance.
What JSON features are supported?
Our formatter supports all standard JSON features including nested objects, arrays, strings, numbers, booleans, and null values. It follows the official JSON specification.
