f you’re anxious to jump into VBA programming, hold your horses. This
chapter is completely devoid of any hands-on training material. It does,
however, contain some essential background information that assists you in
becoming an Excel programmer. In other words, this chapter paves the way
for everything else that follows and gives you a feel for how Excel program-
ming fits into the overall scheme of the universe. It’s not as boring as you
might think.
Okay, So What Is VBA?
VBA, which stands for Visual Basic for Applications, is a programming lan-
guage developed by Microsoft — you know, the company that tries to get you
to buy a new version of Windows every few years. Excel, along with the other
members of Microsoft Office, includes the VBA language (at no extra charge).
In a nutshell, VBA is the tool that people like you and me use to develop pro-
grams that control Excel.
Imagine an intelligent robot that knows all about Excel. This robot can read
instructions, and it can also operate Excel very fast and accurately. When you
want the robot to do something in Excel, you write up a set of robot instruc-
tions by using special codes. Tell the robot to follow your instructions, while
you sit back and drink a glass of lemonade. That’s kind of what VBA is all
about — a code language for robots. Note, however, that Excel does not
come with a robot or lemonade.
