I've worked out a deal with Brainscape, so importing CSVs will be a thing of the past…they will live inside the brainscape app natively.
Give me a week or two – I'll be offering the flashcards via brainscape at a huge, ninja-friendly discount.
When you're working with another entity – sometimes things move slowly to get things done, but the wait will be worth it.
You're welcome to upload your old flashcard files elsewhere via other apps – as long as they are private and aren't publicly shared, for obvious reasons.
