I downloaded open office, because Excel wouldn't show the characters correctly.
I used Calc (open office spreadsheet program) to open the kore.txt file. Choose 'tab' as a separator, and set encoding to UTF 8. Wording might be different because I use a polish version of open office.
Then I deleted all the columns that I didn't need.
Look at the graph cangy linked to, and decide which kanji/word progression you prefer. I decided that the default progression is fine, but if you preref a different one, you have to choose that column in Calc, and sort the list according to it (since I skipped this step I can't tell you what to do step-by-step).
Later save that txt file again, open anki and choose 'import'.
I think here's where you have to build an anki model for your cards. Anki is pretty user friendly so you'll figure it out. Decide what you want to have on your cards, with or without audio and whatnot.
Here's where I am right now, because I can't decide on a model
I hope it helps. Perhaps you can use Excel as well but I'm not into computers and I simply didn't know how to make it show the characters correctly.
edit:
Cangy writes about different plugins. Since I haven't seen the end result yet, I can't tell if what I wrote above is enough to make it work. I downloaded the required plugins from anki website, and put them as-is in the plugins folder in anki directory.
Please correct me if you need to do anything else with them.
