JSON Tree Viewer

Visualize JSON as an interactive collapsible tree — explore complex nested structures with ease.

About JSON Tree Viewer

The JSON Tree Viewer renders your JSON data as an interactive, collapsible tree structure that makes it easy to explore complex nested JSON objects. Each node can be expanded or collapsed individually, and color-coding distinguishes between data types — strings appear in green, numbers in blue, booleans and nulls in orange, object/array keys in purple, and array counts in gray.

This tool is invaluable when working with large API responses, deeply nested configuration files, or any JSON that is too complex to read as raw text. It gives you a visual hierarchy that makes data relationships immediately obvious.

Click any node with a ▶ indicator to expand or collapse it. Use the "Expand All" and "Collapse All" buttons to quickly see the full structure or get a high-level overview. The path to each value is shown on hover, making it easy to write JSONPath expressions.

FAQ

Can I search for a key in the tree?
Use Ctrl+F in your browser to search within the rendered tree. All text in the tree is searchable. For programmatic querying, use the JSON Path Tester tool.
What is the maximum size JSON this can handle?
The tree viewer works well for JSON up to a few MB. Very large JSON with thousands of nodes may render slowly — use the browser's built-in developer tools for extremely large JSON files.
