JSON Tree Viewer - Visualize Structure & Get Paths

What is JSON Tree Viewer?

JSON Tree Viewer is a tool that visualizes JSON data as an expandable and collapsible tree. Data types (string, number, boolean, array, object, null) are distinguished by color coding, and statistics (total key count, maximum depth, type counts) are also available. Clicking a node copies its JSONPath (e.g., $.users[0].name) to the clipboard. It is especially effective for understanding the structure of deeply nested JSON.

How to Use

1. Paste JSON into the text area
2. Click 'Show Tree' button
3. Click nodes to expand/collapse

Usage Examples

Input:
{"users":[{"id":1,"name":"Alice"},{"id":2,"name":"Bob"}]}

Tree view:
▾ users (array: 2 items)
  ▾ [0] (object)
    id: 1 (number)
    name: "Alice" (string)
  ▾ [1] (object)
    id: 2 (number)
    name: "Bob" (string)

Practical use: Understand the structure of a deeply nested API response and copy the JSONPath of the target field to paste into your code

FAQ

Can it display large JSON?

Yes. By default, nodes are expanded to depth 2. Large JSON can be navigated smoothly.

In what format is the JSONPath copied?

In JSONPath format such as $.key.subkey or $.array[0].field. Compatible with major JSONPath libraries like JQuery and JayWay.

How do I expand and collapse nodes?

Click a node to toggle expand/collapse. The initial state shows nodes expanded to depth 2.

Where can I see the number of array elements?

The element count is shown in the array node label. The statistics panel also displays type-based totals.

Is my data sent to a server?

No. All display processing happens entirely in your browser. Sensitive data is safe.
