Does anyone know if Anki or a similar app can handle importing from a text document or spreadsheet?

I have a ton of things I need to learn for my job, and I already have a text document full of notes and definitions. I'd like to assemble everything on my PC and then have flashcards on my phone. I also need to control the syncing because I'd be making cards with the company secret sauce and can't sync to anything but our corporate google drive/docs account.

Having an app that pulls the cards from a google sheets doc would be awesome.
