Frequently Asked Questions
What is JSON formatting?
JSON formatting (also called pretty-printing or beautifying) adds indentation and line breaks to minified JSON data, making it human-readable. This tool formats JSON with customizable indentation (2, 4, or 8 spaces) and optional alphabetical key sorting.
What is JSON minification?
JSON minification removes all unnecessary whitespace, indentation, and line breaks from JSON data, reducing file size for production use. This is the opposite of formatting and is useful for API responses and configuration files where size matters.
How do I validate JSON?
Paste your JSON into the input area and click "Validate". The tool will check the syntax and report whether the JSON is valid or show the exact error location (line and character position) if there are syntax issues like missing commas, brackets, or quotes.
