About the JSON Tree Viewer
Inspect deeply nested JSON as a read-only hierarchy instead of scanning one large text block.
What it does
- Expands or collapses individual objects and arrays.
- Provides Expand all and Collapse all controls for the active tree.
- Searches keys, values and readable paths.
- Moves between matches with Previous and Next while highlighting the active result.
How to use it
- Paste valid JSON and load the tree.
- Open only the branches you need or use the global expansion controls.
- Search and navigate matches to inspect their paths and values.
Notes
The structured view is read-only. Edit the source JSON in the input editor and load the tree again to inspect changes.
Privacy
Tree construction and search happen locally in your browser. The JSON is not uploaded.
