VBA stands for Visual Basic for Applications. It is a scripting language
built into Microsoft Office applications. It allows you to automate some
tasks as well as do some fancy things that are harder or impossible to do
with the regular user interface. You can learn more about it at this link:

While VBA can add a lot of power to Microsoft Office, it has a fairly steep
learning curve.

Terry,

VBA is Visual Basic for Applications. It is also known as macros in MS
Office. VBA is used to create helper programs that can be used for many
different things, such as custom calculations or formatting. For example, I
use it in Word to ensure that hyperlinks in my documents are in synch against
a master list links.

Most MS Office products support VBA development through the macro feature in
the product.
