rpg item database?

Does Unity allow the acces of database programs such as excel, as well as does it also allow for import and export of these file types

You would have to write you’re own pipelines to handle the reading/writing to you’re chosen database program/files. I’ve used the MySql.data.dll in my plugins to access an external MySql server. As for excel there are some 3rd party libraries which you could use as part of your project.
