JSON Viewer – Free Online Tool | TradeInfo.Online
Introduction
JSON (JavaScript Object Notation) is now the de facto format for transmitting structured data between web applications and servers. Whether you’re building APIs, consuming third-party endpoints, or debugging data from a server response, raw JSON is often complex and hard to interpret at a glance.
Enter the JSON Viewer by TradeInfo.Online – a lightweight, web-based tool specifically designed to visualize, navigate, and analyze JSON data effortlessly. Developers, testers, and analysts no longer need to sift through tangled brackets and key-value structures in plain text. This tool neatly displays your data in a tree-like format for quick inspection and validation.
What Is a JSON Viewer?
A JSON viewer is an application that takes a JSON string as input and displays it in a formatted, readable, and often collapsible visual tree. It removes the ambiguity of nested structures and allows users to drill down into each key-value pair easily.
Example:
Raw JSON:
json
CopyEdit
{_x000D_
"user": {_x000D_
"id": 101,_x000D_
"name": "Alice",_x000D_
"details": {_x000D_
"email": "alice@example.com",_x000D_
"active": true_x000D_
}_x000D_
} }
Visual Tree (in JSON Viewer):
user
id: 101
name: Alice
details
email: alice@example.com
active: true
