Welcome to Geoff Lilley's Excel Wiki!

This wiki is designed to be a repository for tips, tricks and ideas. Many of them will be generated by ideas I get from people I work with, from people who took my classes, and people who I've worked with, and asked me a question. Rarely if ever are my ideas completely original; I borrow from other sites and experts, and will make every effort to credit those when I can.

I do not always play with data, but when I do, I prefer Excel.

Stay thirsty, my friends. :)
