This chapter introduces you to Visual Basic for Applications (VBA). VBA is Excel’s programming
language, and it is used to create custom worksheet functions. Before you can create custom
functions by using VBA, you need to have some basic background knowledge of VBA as well as
some familiarity with the Visual Basic Editor.
About VBA
VBA is best thought of as Microsoft’s common application scripting language. VBA is included
with most Office applications, and it’s also available in applications from other vendors. In Excel,
VBA has two primary uses:
h Automating spreadsheet tasks
h Creating custom functions that you can use in your worksheet formulas
Excel also includes another way of creating custom functions by using the XLM macro
language. XLM is pretty much obsolete, but it is still supported for compatibility
purposes. This topic completely ignores the XLM language and focuses on VBA. By the
way, the XLM macro language has absolutely nothing to do with XML, which is a
markup language for storing structured data.
VBA is a complex topic — far too complex to be covered completely in this topic. Because this
book deals with formulas, I hone in on one important (and useful) aspect of VBA — creating
custom worksheet functions. You can use a custom worksheet function (sometimes known as a
userdefined function ) in formulas.
