What is JSON Structure Preview?

JSON Structure Preview is a free online tool that lets you visualize any JSON data as an interactive, collapsible tree. Unlike traditional JSON formatters that only pretty-print your data, this tool shows the full hierarchy with expandable nodes, type highlighting, and one-click path copying.

Key Features

Collapsible tree view: Expand and collapse any object or array node to focus on the data you need.
Syntax highlighting: Strings, numbers, booleans, and null values are color-coded for quick scanning.
Copy paths:Hover over any node and click to copy its dot-notation path (e.g., "config.ocr.engine").
Instant validation: Invalid JSON is caught immediately with clear error messages.

Common Use Cases

Developers use this tool to inspect API responses, debug webhook payloads, explore configuration files, and understand complex nested data structures. It is especially useful when working with deeply nested JSON from document extraction APIs.
