make database email export as csv instead of db

Right now, the export database function can only send a .db file.

This means that the user cannot open the file in Excel or sheets until they first export it as a CSV with SQLiteStudio or similar.

I want to do the conversion in the application so that no extra steps are needed by the user before they can view their data.

I think I should brush up on my data structures and algorithms. I just need to do some sort of map function for the list of objects that I get from the query of the database. But I don't remember how to do this, so I'm just banging my head against the wall.

I'll return to this feature for another attempt after complete the data structures and algorithms again on freecodecamp.
