JSON Tree Viewer

Explore JSON as an expandable tree—click through objects and arrays without reading raw text.

JSON Input

Tree View

Click "View Tree" to visualize JSON structure

Navigate JSON visually

Long JSON strings are hard to scan. The tree viewer parses your document and renders collapsible branches so you can drill into the branch you care about, inspect types at a glance, and collapse noise around large arrays or config blocks.

Good fits

Exploring unfamiliar API responses during integration work
Demoing payload shape to teammates without sharing full raw dumps
Checking nesting depth before choosing flatten or path queries
Reviewing LLM-generated JSON structure before codegen

Root ▼
├─ meta ▼ {object}
│  └─ version: 2
└─ items ▼ [array]
   ├─ [0] ▼ {object}
   │  └─ id: "a1"
   └─ [1] ▼ {object}
      └─ id: "b2"

Practical notes

Paste valid JSON—or repair first if the parser errors on load.
Combine with JSON Search when you know a value but not where it lives.
Very deep trees may need collapsed sections expanded selectively for performance.

Frequently asked questions

Can I copy a subtree from the tree?

Use the formatted output or select nodes as exposed by the tool UI—exact copy actions depend on the viewer controls on the page.

Does it show data types?

Yes. Strings, numbers, booleans, null, objects, and arrays are labeled so you spot type mistakes quickly.

What about invalid JSON?

The tree requires valid input. Run JSON Repair or check the error analyzer, then reload the viewer.
