I happen to like Spolsky a lot but most of the career success we've actually seen from him is managerial, which is not unimportant, but it's not the same as being a dev lead on Excel.
On the other hand, Spolsky's programming advice is much more broad-spectrum and rooted in common sense. I'm not sure you've ever seen Spolsky dismiss a whole category of languages or correctness tools, for instance.
(Microsoft has a more complicated PM scheme with I think two different kinds of PMs? So I can't speak to exactly what Spolsky's role was there. It wasn't a small role, but no, I don't think he led Excel development.)

tl;dr He wrote the spec for VBA, aka Excel Macros. It's not being in charge of all of Excel, but I would call that a pretty substantial contribution.
Bob is more of a theoretical, philosophical guy it seems.
I don't know if I'm just ignorant, but to be honest I have no idea if people like Martin and Fowler can program at all or not!
