I'm supremely interested in why you would want to do this?

There's probably quite a few reasons, all directly related to being able to have ALL module specs onhand, or to work out cost-effective changes. But the former is really important, as that'll certainly include current draws, and having all current draws on the same page is excellent and can help someone plan out their build. They used to have a function here (which is still here, just hidden) known as the "shopping list" that had all of that info on a single, printable spreadsheet-ish output, but I can see why some people might want a spreadsheet to help make final decisions.
