Anki or Quizlet for Flexi Vocab?

So far actually not yet, but thats a great idea. We were thinking about creating decks for Anki or Quizlet. As the Pleco version is paid I thought not so many use it (I might be wrong though?!), though Pleco of course is one of the “essential” Chinese learning apps with it’s dictionaries.

How does it work, is all you need an excel file with the characters, pinyin and English ordered by topic to put in there?
