Frequently Asked Questions
Is this JSON formatter free to use?
Yes! Our JSON formatter is completely free with no registration, limits, or hidden fees. Format and validate unlimited JSON files.
What is JSON formatting?
JSON formatting (or beautifying) adds proper indentation, line breaks, and spacing to make JSON code more readable. Minifying removes all unnecessary whitespace to reduce file size.
Is my JSON data safe and private?
Absolutely. All JSON formatting, validation, and processing happens entirely in your browser using JavaScript. We don't send, store, or process your data on our servers.
Can this tool validate JSON syntax?
Yes! The tool automatically validates JSON syntax and shows detailed error messages if your JSON is invalid, including the line number and error description.
What is the difference between format and minify?
Format (beautify) adds indentation and line breaks for human readability. Minify removes all whitespace to create the smallest possible file size for production use or API transmission.
