My Excel hacking is pretty limited, but I do know some basic stuff about it. I got to thinking about the "import/export" problem (the lack of being able to do it), and thought that maybe there should be an import export tab at the bottom.
The export tab would basically be a single column which would include all the basics:
Elf
Warlord
Tactical Pressence
18
14
16
ECT...
Which you could then just highlight the entire column and place it into the "import" tab of the new updated Version XX.X sheet. I'm not sure if you'd have to use a macro to pull all the data back into the sheet, but it seems that this would be a very quick and easy way for an end user to import and export data. If i'm wrong and this is a huge pain in the a$$, then i apologize for not doing my due research. ;-)
As far as the sheet goes, I'm extremly impressed with it despite known bugs. I'm starting a campaign with 5 of my friends (2 girls who have never played before!), and I think this sheet with "power" features will make things much easier for the newbs to understand how the game works. As soon as funds become available I'll try to drop a small donation your way, but as it stands now i'm poor and I would rather eat dinner. Keep up the good work!
