What is JSON Analyzer?

JSON Analyzer parses your JSON input and displays it as a hierarchical tree, making it easy to explore the structure at a glance. Each key is paired with its value type, and nested objects and arrays can be expanded or collapsed interactively.

How to Use

1. Paste your JSON into the input field above.
2. Click "Analyze" to parse and display the structure.
3. Click any key in the tree to expand or collapse its contents.
