>I feel the major issue with excel (and other stuff such as CSS) is that one learns by cobbling things together and never through a formal process.

This is literally all programming, and it's not necessarily a bad thing. As long as you keep learning and don't just keep doing the same cobbled together mess for years and years

I disagree, in my experience most people I know who learned ruby, python, java, C or other programming languages went through some book or tutorial.

Many of the people who write CSS or use Excel have never read a book about CSS or Excel.
