Input JSON
Formatted JSON (Tree View)
Why Use an Advanced JSON Formatter?
While a simple text formatter is useful, an advanced JSON viewer with a collapsible tree is a game-changer for developers working with complex, nested data. It transforms a confusing wall of text into a navigable structure.
- Interactive Tree View: Easily expand and collapse nodes to explore nested objects and arrays without losing your place.
- Instant Validation: The tool validates your JSON as you type, immediately highlighting any syntax errors.
- Fast & Client-Side: All formatting and validation happens in your browser. Your data is never sent to a server, ensuring 100% privacy and instant results.
- Minify & Beautify: Switch between human-readable (beautified) and compact (minified) JSON with a single click.
