I understand the author isn't updating anymore so there are a few things you should look out for while you're using the 2007 version:
First of all some of the enchants aren't in the game yet or have been changed since beta and are not reflected on the sheet, you may change these on the gear page by scrolling down or to the right to change/add/replace items/enchants/gems.
Second of all, my base stats were different than what was already input for an Orc which lead to about 2k missing hp, you may edit these on the race page and put in your own base values.
I haven't managed to get it exactly right but the numbers are close enough to give you a good feeling as to how your gear's going to hold up, pretty useful spread sheet.
Edit: Also found that cell L11 under the gear sheet's formula is
=VLOOKUP(Helm,TGear,18,FALSE)+IF(C11="Yes",VLOOKUP(Helm,TGear,19,FALSE),0)
but should be
=VLOOKUP(B11,TGear,18,FALSE)+IF(C11="Yes",VLOOKUP(B11,TGear,19,FALSE),0)
This was causing Boundless Ambition to not grab the expertise rating it had from the item list.
