JSON Formatter FAQ
What's the difference between Beautify and Minify?
Beautify adds indentation and line breaks to make JSON human-readable. Minify removes all unnecessary whitespace to create the smallest possible file size, ideal for production use.
Is my JSON data secure?
Yes! All processing happens directly in your browser. Your data never leaves your device and is not sent to any server.
Can I use tabs instead of spaces?
Yes! Select 'Tab' from the indentation options to use tab characters instead of spaces for indentation.
