JSON Viewer
Explore JSON as an interactive tree. Expand and collapse nodes, search keys and values, and copy paths — all in your browser.
Input
Your JSON is processed locally in your browser. We don't upload your JSON to any server.
Why use a tree view?
Large JSON documents are hard to read as plain text. A tree view collapses nested objects and arrays so you can focus on one branch at a time. This viewer renders nodes lazily, so even big structures stay responsive — collapsed branches are not drawn until you open them.
Working with the tree
- Expand / collapse — click the triangle next to any object or array.
- Expand all / collapse all — jump between an overview and full detail.
- Search — filter keys and values; matches are highlighted and their ancestors auto-expand.
The viewer builds its tree from your input in the browser, so nothing is sent anywhere.
