Format, validate, and minify JSON with real-time syntax highlighting
JSON formatting (beautifying) converts compact or minified JSON into a readable format with proper indentation and line breaks. Our JSON formatter organizes your data with 2-space indentation, making it easy to read nested structures, objects, and arrays. It's essential for debugging and reviewing JSON data.
To validate JSON: 1) Paste your JSON in the input editor, 2) Click the 'Validate' button or the tool will auto-validate as you type. If there are errors, they'll be highlighted with line numbers and descriptive error messages. Valid JSON will show a success notification.
JSON minification removes all unnecessary whitespace, line breaks, and formatting from JSON data, reducing file size for faster transmission and storage. Minified JSON is ideal for production APIs, configuration files, and web applications where bandwidth matters. Use the 'Minify' button to compress your JSON.
Flattening converts nested JSON objects into a single-level object using dot notation for keys. For example, {user: {name: 'John'}} becomes {'user.name': 'John'}. Click the 'Flatten JSON' button to convert nested structures. This is useful for databases, CSV exports, and data analysis.
JSON escape converts a JSON string into a format safe for embedding in other JSON or strings (escaping quotes, backslashes). JSON unescape reverses this process. Use 'Escape JSON' to prepare data for APIs or databases, and 'Unescape JSON' to make escaped strings readable again.
Yes! Click the 'Sort Keys' button to alphabetically sort all keys in your JSON, including nested objects. This makes JSON easier to compare, diff, and version control. The sorting is recursive, organizing keys at every level of your data structure.
Use the 'Remove Comments' button to strip single-line (//) and multi-line (/* */) comments from JSON5 format. This converts JSON5 to standard JSON. The tool also removes trailing commas that may cause validation errors in strict JSON parsers.
Yes! All JSON processing happens locally in your browser using JavaScript. Your data is never uploaded to our servers or transmitted anywhere. The tool works completely offline once loaded, ensuring your JSON data remains private and secure on your device.
