What is JSON Tree Viewer?
JSON Tree Viewer renders complex, deeply nested JSON data structures as an interactive, collapsible tree hierarchy. Rather than scrolling through thousands of lines of raw text, developers can visually expand and collapse specific branches, inspect data types, and explore arrays and objects with ease. Operates 100% client-side for confidential API payloads and logs.
How to use JSON Tree Viewer
- 1Paste raw or minified JSON text into the input editor.
- 2The interactive tree mounts immediately in the result panel.
- 3Click on object keys or array brackets to expand and collapse nested branches.
