BlueprintJSON

BlueprintJSON is a full and simple JSON library for Blueprints. Bring the power of JSON into your Unreal Engine Blueprint project.

Read and Parse JSON

BlueprintJSON allows you to read JSON files or parse directly JSON from a string.

Edit and save JSON

BlueprintJSON allows you to edit JSON at runtime and save it directly to a file.

Asynchronous

BlueprintJSON offers several asynchronous blueprint nodes to perform the heavy JSON processing outside of the Game Thread. This way, you can load or save several big JSON files in parallel without worrying to block the Game Thread.
