FAQ

How do I visualize JSON structure?

On the DevTools JSON Tree Viewer page, paste JSON and click Render Tree to browse the full structure interactively.

Does the tree view modify my data?

No. The tool is read-only and does not change the original JSON.

How large a JSON document can it handle?

Depends on browser performance. Very deep nesting or huge arrays may render slowly.

Is rendering done on a server?

No. Parsing and rendering happen locally in your browser.
