How It Works
- Paste and format: paste any JSON and it is automatically prettified with 2-space indentation
- Syntax highlighting: keys, strings, numbers, booleans, and nulls are each color-coded for readability
- Validation: invalid JSON is caught instantly with error messages pointing to the exact line and position
- Minify: compress JSON to a single line by removing all whitespace, ideal for APIs and config files
- Copy: one-click copy of the formatted or minified output to your clipboard
- Keyboard shortcut: press Ctrl+Enter (Cmd+Enter on Mac) to format instantly
- Privacy: everything runs in your browser. Your JSON is never sent to any server.
