Paste JSON data to format it with proper indentation, validate its structure, or minify it for production use. Supports 2-space, 4-space, and tab indentation.
A JSON formatter takes raw or minified JSON data and transforms it into a well-structured, readable format with proper indentation and syntax highlighting. This is an essential tool for developers working with APIs, configuration files, and data exchange formats. Our browser-based JSON formatter validates your JSON syntax in real-time, highlights errors, and lets you switch between formatted and minified views. All processing runs entirely in your browser, ensuring your sensitive API data and configuration files remain private.
JSON formatting (or pretty-printing) adds proper indentation and line breaks to make JSON data human-readable.
Minification removes all unnecessary whitespace and line breaks from JSON, reducing file size for production use.
Our tool checks if the input follows valid JSON syntax. If there's an error, it shows the position where the problem was detected.
Absolutely. All processing happens in your browser. Your JSON data is never sent to any server.
