What is JSON Formatter?
JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. However, JSON data returned from APIs is often "minified" (compressed into a single line) to save bandwidth, making it extremely difficult to read.
Key Features
- Beautify: Formats minified JSON into a readable tree structure with proper indentation.
- Validate: Automatically checks for syntax errors (missing commas, unclosed brackets) and alerts you instantly.
- Minify: Removes all whitespace and newlines to reduce file size for production use.
- Secure: All processing is done client-side in your browser. Your data is never sent to our servers.
How to use?
Simply paste your JSON code into the editor above or upload a .json file. Click "Format" to beautify it or "Minify" to compress it. If there is an error in your code, the tool will highlight it immediately.
