Does anyone know where I might find an excel file, or something similar, to calculate custom profiles?

I have no idea but I could use it myself.

So whoever has it, you'll make me happy as well.

It is hard, if not impossible, to create a reliable profile generator because the game is not mathematically balanced.
Like most GW games it started out balanced. You COULD figure out what profiles equaled what profile levels. However, over time the profiles have abandoned mathematical balance and stat creep has occurred. Now the game isn't as far out of whack as WHFB or (ugh) 40k, but it is still not balanced.
You can kind of figure out a point value for models, but some are very far out of line.

I am considering making a set of house rules with concrete point values assigned to profiles/special abilities. This would reassign point value to every model in the game, but it would be close to the current levels.

I am not sure but if you mean for army building all you want is right here:

This is exactly why I'm asking the question, lol.

Thank you everyone for the quick replies.
