In short you don't... Making money using excel is like saying "how do I make money from knowing how to use a hammer". You don't.
People pay based on value, but knowing how to use a tool is a tiny slice of value, knowing what to direct it to and the nuances of a particular niche are what starts to bring value.
So for a good hammer user, maybe its finding someone else who needs a hammerer (e.g. a builder) and getting a job with him. Maybe its learning the other skills of carpentry or joining so you can make furniture, or maybe its more entrepreneurial and smashing up ice to make slushy drinks.
The other answers mension things that although they use excel, the skillset is MUCH wider than that -- e.g. teaching >> knowing. Take a look at all the stuff chandoo.org needs to do to make money.
'Consulting' requires things like finance or operational knowledge coupled with excel. Again the excel bit is minor, and often done by junior people in firms.
The best you can hope for without further skills or vision is a job or freelance work fixing peoples sheets and macro's etc. even then though the skill is diagnosing the problem.
Excel is a tool, tool usage has no value until its applied somewhere; and excel is used VERY widely so you can pick an area and then start building the other skills and connections to make value.
