Explore JSON as a live, collapsible tree — click any node to see and copy its JSONPath, no button to click, and the top level opens automatically while nested branches stay collapsed for large files.

How it works

Paste your JSON
The tree renders live below — the top level expands automatically, nested branches start collapsed
Click any node to see its JSONPath (e.g. $.items[2].name) and copy it with one click

Frequently asked questions

Does it update as I type?

Yes — no button to click. The tree re-renders live as you paste or edit your JSON.

How do I get the path to a specific value?

Click any node in the tree — its JSONPath appears in a bar above the tree with a Copy path button, ready to paste into your code.

Will a large JSON file slow down my browser?

Only the top level expands automatically; nested branches start collapsed, which keeps the initial render fast even for large documents. Use Expand all if you need to see everything at once.

Most JSON tree viewers make you click a button, then count brackets by hand to find a value's path. Ours gives you both instantly.

We checked jsonlint.com's tree viewer directly — it needs a 'View Tree' click before anything renders, and clicking a node never tells you its path. Ours renders live as you type, and clicking any node shows (and lets you copy) its exact JSONPath.
