JSON Visualizer

Paste JSON and explore it as an interactive node graph or a collapsible tree. Pan, zoom, search and copy any value or path — all in your browser.

How it works

  1. 1

    Paste JSON

    Drop any JSON document into the input. It is parsed instantly, with a clear error if anything is malformed.

  2. 2

    Pick a view

    Switch between a node graph that maps the structure visually and a collapsible tree for line-by-line inspection.

  3. 3

    Explore

    Pan and zoom the graph, expand or collapse branches, and click any node to copy its value or its dot-path.

Instant & 100% private — nothing is uploaded

Everything runs locally in your browser. Your code, text and files are processed on your own device and are never sent to a server — so there are no upload waits, no size limits from us, and nothing is ever stored or logged.

Frequently asked questions

How is this different from a JSON formatter?
A formatter pretty-prints the text. The visualizer maps the relationships — objects and arrays become connected nodes you can pan and zoom, which makes the shape of deeply nested data far easier to grasp.
Can I copy the path to a value?
Yes. Click any node and copy either its value or its full dot/bracket path (for example data.items[0].id), ready to paste into code or a query.
How big a document can it handle?
Because it runs locally, the limit is your device’s memory, not an upload cap. The tree handles very large files comfortably; the graph is best for documents up to a few thousand nodes.
Is my data sent to a server?
No. Everything runs locally in your browser using JavaScript and WebAssembly. Your input never leaves your device, nothing is uploaded, and nothing is logged or stored.
