JSON Visualizer

Visualize and edit JSON, YAML and XML as an interactive node graph. Opens from the toolbar.

Turn JSON, YAML and XML into an interactive node graph — and edit it visually. JSON Visualizer opens your data as a clean, pannable graph so you can understand its structure at a glance. Click any value to edit it, add or remove fields right on the graph, and export back to JSON, YAML, XML or CSV. FEATURES Interactive node graph — pan, zoom, fit-to-screen, and a one-click walkthrough that glides through your data node by node Two-way editing — edit values directly on the graph or in the text pane; both stay in sync Native formats — view and edit JSON, YAML and XML in their real format, and switch between them instantly Search — find any key or value and jump between matches Collapse / expand — fold large structures down to what matters Big-file friendly — only renders what's on screen, so large files stay smooth Export — JSON (pretty or minified), YAML, XML or CSV Precise error locator — invalid JSON points you to the exact line and column 100% LOCAL & PRIVATE Your data never leaves your machine. No servers, no tracking, no account. The extension requests no permissions and works entirely offline. Open it from the toolbar, paste or open a file, and explore.
