About JSON Crack — Interactive JSON Graph Visualizer
JSON Crack turns JSON, YAML, XML, or CSV into an interactive, zoomable node graph, making it much easier to explore deeply nested structures than scrolling through raw text. Pan, zoom, and click into nodes to trace relationships between fields. The build here is self-hosted directly from the JSON Crack project's own source and runs entirely client-side: nothing you paste is ever uploaded.
How to use
- Paste or upload your JSON, YAML, XML, or CSV data into the editor pane.
- The graph renders automatically on the canvas — pan and zoom to explore nested nodes.
- Click a node to expand or collapse it, or jump to its raw value in the editor pane.
Frequently asked questions
- Is my data uploaded anywhere?
- No. Parsing and graph rendering happen entirely in your browser via JavaScript — nothing you paste is sent to a server, including by this site.
- What formats are supported?
- JSON, YAML, XML, and CSV can all be visualized as a graph.
- Is there a size limit?
- Very large documents may render slowly since everything runs client-side, but typical API responses and config files work smoothly.
