Frequently Asked Questions
What is JSON formatting?
JSON formatting is the process of organizing JSON data with proper indentation, line breaks, and spacing to make it more readable. Our formatter also validates JSON syntax and can minify code for production use.
How do I fix invalid JSON?
Our tool automatically detects JSON errors and shows the exact line and position of the problem. Common issues include missing quotes, trailing commas, and unescaped characters. Use the Auto-Fix feature for automatic corrections.
What's the difference between format and minify?
Formatting adds indentation and line breaks for readability, while minifying removes all unnecessary whitespace to reduce file size. Use formatted JSON for development and minified JSON for production.
Is my JSON data secure?
Yes, all JSON processing happens entirely in your browser. Your data is never sent to any server, ensuring complete privacy and security for sensitive information.
Can I customize the indentation?
Yes! You can choose between 2-space, 4-space, or tab indentation. Select your preferred option from the indent size dropdown before formatting.
