UE5 C++ 5 - How To Read and Write Data Table Json with C++? - Unreal Engine Tutorial Editor CPP

Because Jsons files that are generated using a DataTable are formatted completely differently from a normal Json file, we need new functions to read and write them.

At 0:28 in your video, you show to versions of JSON. On the left right side, it shows the vector, rotator and transform data in string format. This is the same format I see when I do a myTable->GetTableAsJSON().

Is there a way to get the JSON out of the table where it does not put TArray<MyVector> (in your case) in string format?
I know that if you are in the editor, right click on a table and export it out, it will export all the json in the proper hierarchical format like you have shown in your left side window.

The reason I'm trying to figure this out is because unfortunately the structures that are used in the data table I'm trying to pull data out of were defined in the editor, no down in C++... And trying to refactor all those structs and tables to use C++ structs will be a pretty big task that I'm not sure the business will give us time to do.

Hi! How do you name C++ scripts with a number at the beginning? UE tells me it's not possible. Also the name of your class exceeds 32 characters limit, I had to rename by hand after creation outside of UE to have the same name than you. Thanks!
