The JSON Tree Viewer is a lightweight Unreal Engine plugin that brings JSON data to life with a collapsible tree view. Simply feed it a JSON string or file path, and it will parse and render your data hierarchically in-editor or at runtime.

Features:

Easy integration as a UWidget or Blueprint component
Customizable styling: control colors for keys, values, nulls, and special “@” properties, along with padding and font settings
Dynamic parsing: supports all JSON types (objects, arrays, strings, numbers, booleans, null)
Blueprint-friendly API: expose file loading and tree initialization calls directly in Blueprints
