When dealing with deeply nested JSON objects, a plain text view can be overwhelming and difficult to navigate. A JSON Tree Viewer provides a visual, interactive representation of the data's structure. It displays the JSON as a hierarchical tree of nodes, where each key-value pair, array, or object is a distinct, expandable branch. This allows developers to quickly grasp the relationships between different parts of the data, collapse irrelevant sections to focus on what matters, and drill down into specific nested values. It is an indispensable tool for understanding the schema of an unknown API response, debugging data-related issues, or simply getting a high-level overview of a complex configuration file without getting lost in a sea of brackets and braces.
