I totally agree, for something as simple as collecting and parsing a CSV something like Flutter would do me much better. Im using Unreal because frankly, Blueprints is all I’m able to code with 
I have issues with reading and writing, so written spricts are a nightmare. I know Godot has a visual code plugin though, so I’ve been looking into that. But some of the more specific functions like pulling a Google Sheet and other similar functions would require writing out scripts. Meanwhile UE has a Blueprints plugin just for that.
As for future use though, I do have ideas for things like AR model viewing, and 3D interactive Clade Trees. Just ideas though, but somethine like that would definetly be harder to code in something like Flutter, so I’m gonna try to stick with either Unreal or Godot.
The keyword JSON keeps popping up in my searches and other people’s responses, so I’ll look into that and see what I can do with it. Thanks for the pointer :3
