I have an RTK Lite spreadsheet based on nukemarine's idea of learning by Kanji Odyssey 2001 group.
Here's the text file with tab separated values. It should open in any text editor (has UTF-8 encoding and Unix [LF] line breaks). Just open and copy-paste into a spreadsheet application like Excel. Or, it can be imported into Anki (but remove the column headers first).
See my previous post for what the group numbers mean and a link to a pre-made Anki deck.
