Press Ctrl+V or Cmd+V on the tree to open your own JSON.
How do I view JSON as a tree?
Paste JSON while you're in Tree view and it opens in a new tab as a collapsible tree, where every object and array folds open and closed. That makes it easy to find your way around a big API response without scrolling through thousands of lines.
Right-click any node to copy its path as JSONPath, JavaScript, jq or JSON Pointer, or to copy the key or value. Switch to Code view to edit the JSON, or Flow view to see the same data as a graph.
- Press Ctrl+V or Cmd+V on the tree, or drop a .json file onto the page.
- Click any object or array to expand or collapse it.
- Right-click a node to copy its path or value.
Questions people ask
How do I copy the path to a value?
Right-click it in the tree and choose Copy path for JSONPath, or Copy path as for JavaScript, jq or JSON Pointer.
Can I edit JSON in the tree?
The tree is for reading. Switch to Code view to edit, or to Flow view, where you can change values right on the graph.
How large a file can it open?
It runs in your browser, so your machine's memory is the limit. Deeper levels of the tree stay folded until you open them, which keeps big documents responsive.
Is my data uploaded anywhere?
No, this runs entirely in your browser, so nothing you paste is sent to a server. The only feature that sends data anywhere is the optional AI assistant, and only when you actually ask it something.
