JSON is Hard to Read. This Makes It Easy.
You get a JSON response from an API. It's a wall of text with brackets, commas, and nested objects. You scan it, but it's hard to see the structure. You need to find a specific value, but you're scrolling up and down.
This tool turns JSON into an interactive tree. You can expand and collapse nodes, copy values with one click, and see the structure clearly. It's the fastest way to understand any JSON data.

Explore the tree — Click on any node to expand or collapse it. The structure becomes clear instantly.
Copy values — Hover over any value and click the copy button. The value is copied to your clipboard.
Format your JSON — Click "Format JSON" to clean up messy or minified JSON.

Frequently Asked Questions
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data format used for APIs, configuration files, and data storage. It's human-readable but can become hard to parse when it's deeply nested or minified.
Is my JSON data shared or stored?
No. All processing happens in your browser. Your JSON is never sent anywhere, stored, or logged. Everything stays on your device.
Can I copy values from the tree view?
Yes. Hover over any value and click the copy button that appears. The value is copied to your clipboard.
What happens if I paste invalid JSON?
The tool will show an error message with details about what's wrong. You can fix the JSON and try again.
