Frequently Asked Questions
What is a JSON Formatter?
A JSON Formatter takes your JSON data and reformats it for better readability. It can add proper indentation (beautify) or remove all whitespace (minify), making JSON easier to read or smaller in size.
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 reduce file size, which is useful for production code and API responses.
Can I customize the indentation?
Yes! You can choose between 2 spaces, 4 spaces, or tabs for indentation. This helps match your project's coding style or personal preference.
What does 'Sort Keys' do?
The Sort Keys option alphabetically sorts all object keys in your JSON. This is useful for comparing JSON files, maintaining consistency, or making data easier to find.
Is my JSON data secure?
Absolutely. All formatting happens directly in your browser - your data is never sent to any server. Your JSON stays completely private and secure.
