About JSON Viewer
Paste JSON and navigate it as an interactive tree. Expand and collapse nested objects, search for specific keys, and understand complex data structures at a glance.

Examples
Tree view vs raw JSON
Compare how the same data looks:
Raw JSON (hard to read):
{"users":[{"id":1,"name":"Alice","roles":["admin"]}]}
Tree View:
▾ users (1 item)
▾ 0
id: 1
name: "Alice"
▾ roles (1 item)
0: "admin"Identifying data types
Types are color-coded for quick scanning:
{
"name": "Alice" → string (green)
"age": 30 → number (blue)
"active": true → boolean (purple)
"manager": null → null (gray)
"roles": [...] → array (shows count)
"profile": {...} → object (expandable)
}Navigating large arrays
Quickly see array sizes without expanding:
▾ data ▸ users (1,523 items) ← click to expand ▸ products (847 items) ▸ orders (12,405 items) Expand only what you need
