JSON Visualizer
Render any JSON document as a visual node graph you can expand and collapse, instead of scanning raw indentation. Makes deeply nested structures far easier to navigate than a flat tree view.
Paste JSON and it renders as a graph of connected nodes — objects and arrays as expandable boxes, primitive values as leaves. Click any node to collapse or expand its children and focus on the part you care about.

Frequently asked questions
How is this different from the JSON Formatter's tree view?
The tree view shows a linear, indented outline. The visualizer lays nodes out as a connected graph with explicit parent-child lines, which tends to make wide or deeply branching structures easier to scan at a glance.
Does it handle large JSON documents?
Yes, though very large documents (tens of thousands of nodes) render faster with the top-level nodes collapsed by default — expand only the branches you need to inspect.
Is my JSON uploaded anywhere?
No — the graph is computed and rendered entirely in your browser. Nothing is sent to a server.
