Introduction to VBA
What VBA automates, and your first macro.
VBA (Visual Basic for Applications) is the scripting language built into Excel (and other Office apps) for automating repetitive tasks — anything you can do by clicking, VBA can usually do programmatically.
A macro is just a VBA `Sub` procedure: `Sub SayHello()` ... `End Sub`. You can run it directly from the VBA editor, or bind it to a button on a worksheet.
VBA scripts commonly work with Range objects to read and write cell values: `Range("A1").Value = "Hello"` sets cell A1's content directly, the same result as typing it in by hand.
