About JSON → Graph
JSON Graph converts any JSON structure into a live interactive node-link graph powered by JsonCrack. Every object and array becomes a connected node, and every key-value relationship becomes a labeled edge between them. Zoom and pan freely to explore the full topology of your data, then export the result as a crisp SVG or PNG for documentation or presentations. Paste any JSON on the left and the graph updates instantly on the right.
Features
- ✓JsonCrack-powered interactive node-link graph rendering
- ✓Automatic layout that separates and connects nested objects and arrays
- ✓Labeled edges showing the property name linking parent to child
- ✓Zoom and pan canvas navigation
- ✓Live update — graph re-renders as you edit the JSON input
- ✓Export graph as SVG (vector, scales to any size)
- ✓Export graph as PNG (rasterized snapshot)
- ✓JSON editor with syntax highlighting and inline error feedback
Common Use Cases
- Visualizing the relational structure of a complex API response
- Understanding the topology of deeply nested configuration objects
- Creating visual documentation of JSON data structures for presentations
- Identifying deeply coupled or isolated properties in a schema at a glance
- Quickly grasping the shape of an unfamiliar JSON payload
Frequently Asked Questions
QHow are arrays represented in the graph?
Array elements are rendered as indexed child nodes (e.g. `[0]`, `[1]`) connected to the parent array node, keeping the graph navigable without collapsing array content.
QWhat export formats are supported?
You can export the current graph as an SVG vector file (scales to any size without pixelation) or a rasterized PNG snapshot.
QIs there a size limit on the JSON?
Very large JSON files with hundreds of nodes may slow down the layout engine. For best performance, paste the relevant subtree rather than an entire large payload.
QWhat is the difference between this tool and JSON Visualizer?
JSON Graph shows only the node-link graph view. JSON Visualizer combines the same graph view with a UML class diagram tab and 9-language code generation in a single tool.
