FString JsonString = TEXT(“YOUR_JSON_STRING”);
TSharedRef< TJsonReader<> > Reader = TJsonReaderFactory<>::Create(*JsonString);
if (FJsonSerializer::Deserialize(Reader, JsonObj) && JsonObj.IsValid())
{
// All is okay, json is valid
JsonObj->GetArrayField(…); // get the array field
// @todo process it now as u want
}
