I tried doing this a couple of years ago and couldn't make it work. I've just spent another 5 hours trying to import Greek vocab lists into my Esperanto slot and still can't make it work. I'm on Windows 7 and have tried every help on all the posts I could find: using Notepad, using Excel, renaming it, filling in all 3 spaces with text, commas, quotations, quotations with commas, UTF-8 encoding, etc.
Very frustrated b/c I'm a software engineering student and should be able to do this! Any ideas that I didn't mention? It seems like many people can't make it work. I learned Greek in seminary and really want to continue by importing word lists from Perseus, but nothing seems to work. Thanks for any help.
