While those are useful, the PDF one requires downloading of a program to download the PDF.. so it's a little fishy to me.
The Excel one seems fine, but for ease of use, would have to be printed into a PDF file via a PDF-printer program.
Otherwise, good finds.
These are some of the greatest books for D&D because it compiles so much information in a usable form. Some things were over powered and others were just wacky so the players had no idea if what they found would be useful or deadly to them.
