D&D 3.5e Character Sheets in Excel (automated)

I'm looking for said excel files that allows you to input numbers and it does all the calculations for you.

However I also want to be able to modified the sheet so I can set it up for House Rules in case a DM has changed a few things to the basic rules.

Does anyone know where I can find 3.5e sheets?

 

try googling heroforge. As far as i know there was a DnD one and a SWRCR one. I don't know for definite if it's 3.5e though
