How can I download a memrise course to excel or csv format?

Hi, I have just purchased memrise pro membership as I want to learn a new language. There are too many courses already available BUT I would like to make some changes to them. Hence my question, How can I download an existing / already created memrise course to excel or csv or any other format?

It would have been super cool if I could just make a copy from existing courses and improve on them. Just like how GPL and MIT licensed content works
