🧬 JSON Graph Visualizer
Visualize JSON data as an interactive node graph with zoom, drag, and collapsible branches
About this tool
This tool renders JSON data as an interactive graph where each object, array, and leaf value becomes a node, and parent-child relationships are drawn as edges. Drag to pan, scroll to zoom, and click any container node (object or array) to collapse or expand its children — a fast way to visually explore deeply nested structures.
Example: paste the JSON {"store": {"books": [{"title": "Dune", "price": 19.99}, {"title": "1984", "price": 12.49}]}} and click Visualize. You'll see a graph with a "store" object node containing a "books" array, each book as a child node, and leaf nodes for title and price strings and numbers. Click the "books" node to collapse all book entries, then expand them one at a time.
Different node shapes and colors distinguish JSON types: boxes for objects and arrays, ellipses for leaf values; blue for objects, green for arrays, orange for strings, purple for numbers. This makes it easy to spot patterns — for example, a cluster of purple number nodes under a green array node tells you it's an array of numbers.
Search for nodes by name or path, and click any node to see its JSONPath and copy it to your clipboard. The whole graph is interactive — drag to rearrange disconnected components, scroll to zoom in and out, and use the Fit button to center everything in view.
FAQ
Does this tool send my JSON anywhere? ›
No. All JSON parsing and graph rendering happens entirely in your browser. The only external resource loaded is the vis-network visualization library from a CDN for rendering the graph — no data is ever transmitted.
How is this different from the JSON Tree Explorer? ›
The <a href="/json-tree-viewer" class="text-accent hover:underline">JSON Tree Explorer</a> shows a linear collapsible tree with indentation — great for reading through a payload in order. The Graph Visualizer maps JSON to a 2D node-edge diagram where you see the overall shape at a glance: deeply nested structures look like chains, wide arrays spread across the canvas, and disconnected subtrees are immediately obvious. Use the Tree Explorer for sequential reading, the Graph Visualizer for structural overview.
What does collapsing a node do? ›
Clicking a box-shaped node (object or array) hides all its descendant nodes and their connecting edges, clearing the view so you can focus on the higher-level structure. Click it again to restore them. This is especially useful for large JSON payloads — collapse irrelevant branches and expand only the parts you care about.
Can I export the graph as an image? ›
Not directly from this tool. You can use your browser's screenshot tool or developer tools to capture the canvas. For programmatic graph export, consider using a diagramming tool that supports JSON import.
