JSON Visualizer & Interactive Tree Viewer
Inspect, collapse, and copy node paths from raw JSON payloads interactively 100% in your browser.
Interactive JSON Object Tree Viewer & Path Extractor
Visualize nested JSON objects and arrays in a structured tree graph with syntax color coding and node path extraction.
1. Collapsible Nodes
Expand and collapse deep object trees to inspect specific key-value properties cleanly.
2. One-Click Path Copying
Hover over any property node to copy its dot-notation accessor path (e.g. settings.theme).
3. Private Parsing
All JSON parsing runs natively in JavaScript local memory without server network transmission.
About the JSON Visualizer
The JSON Visualizer renders a document as an expandable tree so you can explore structure instead of scrolling raw text. Collapse branches you do not care about, expand the one array element you do, and see at a glance which values are strings, numbers, booleans or null. It is particularly useful for deeply nested API responses where finding the path to a single field in a formatted dump is slow.
How to use the JSON Visualizer
- Paste your JSON document into the input panel.
- Expand and collapse nodes to navigate the structure.
- Inspect value types and copy the data you need.
Frequently asked questions
How is this different from a JSON formatter?
A formatter pretty-prints the full document as text, which still means scrolling. The visualizer builds an interactive tree you can collapse, so a 5,000-line response reduces to a handful of top-level nodes you expand on demand.
Can it handle large API responses?
Yes. Collapsed branches are not rendered, so large documents stay responsive. Everything is processed in your browser with no upload step.
Will it show me invalid JSON?
Invalid input cannot be turned into a tree, so a parse error with its position is shown instead. Run the document through the Code Formatter to locate and fix the syntax problem first.
