One of the first things I learned stepping into the office place is that my overpriced comparative literature degree wasn't going to get my very far. Knowing Excel would. It's pretty amazing what can be done with the program. And perhaps even more amazing
how few people know how to go beyond the basics.
The guys at Juice Analytics did a great job of putting together this Excel Training Worksheet. The tutorial is presented in a workbook download, with each sheet covering a topic like VLookups, Conditional Formatting, or In-Cell Graphics. Whether you're a newbie or a VBA wizard, I promise you'll find something in here you didn't know before.
