Fast JSON data asset management, deep path queries, and automatic struct serialization in Unreal Engine.

Welcome to EasyJson

EasyJson makes working with JSON in Unreal Engine fast, intuitive, and crash-proof. It introduces first-class JSON Data Assets in the Content Browser, deep dot-notation queries, and instant wildcard struct serialization for Blueprints and C++.

No More String Parsing Headaches:
Stop manually building JSON strings or looping through raw json objects. With EasyJson, you can read nested values with dot syntax like player.stats.health or convert entire structs with a single node.

What is EasyJson?#

Standard Unreal Engine JSON handling requires writing lengthy C++ helper functions or installing complex third-party libraries that clutter your project.

EasyJson streamlines the entire process:

  • JSON Data Assets: Create .json assets directly in your Content Browser with syntax highlighting and validation in the Details panel.
  • Deep Path Queries: Fetch or update values using dot and bracket notation (e.g., inventory[2].item_id).
  • Wildcard Struct Conversion: Automatically serialize any Blueprint struct to JSON, or deserialize JSON back into your struct with full type safety.
  • HTTP Ready: Easily parse REST API responses and backend game configurations.
