The JSON Tree Viewer is a lightweight Unreal Engine plugin that brings JSON data to life with a collapsible tree view widget. It was developed to support developers who may not be comfortable working in C++ but have working knowledge of Blueprints. This plugin aims to enhance efficiency and convenience for these developers. Simply feed it a JSON string or file path, and it will parse and render your data hierarchically in-editor or at runtime. The tree view widget was created in Slate for maximum performance but is accessible via blueprints for ease of use. The source code is available here for those who wish to review or utilize specific components: JSON Tree Viewer.
