When a formatter isn't enough
A formatter shows you the shape of your JSON. A viewer lets you navigate it. If you're working with a deeply nested API response — say, a Stripe webhook or a GraphQL result with several layers of objects — scrolling through indented text to find a specific value is slow. The tree view lets you collapse the parts you don't care about and focus on what you're actually looking for.
How it works
Paste or type JSON in the left editor. The tree on the right updates as you type. Objects show their keys as expandable nodes, arrays show their indices, and primitive values (strings, numbers, booleans, nulls) sit at the leaves. Click any node to expand or collapse it.
If the JSON is invalid, the tree clears silently — no error banner in the way. Fix the syntax in the editor and the tree comes back immediately.
