automatically execute an Excel macro on a cell change

Question

How can I automatically execute an Excel macro each time a value in a particular cell changes?

Right now, my working code is:

Private Sub Worksheet_C         


        

Answer 1

Handle the Worksheet_Change event or the Workbook_SheetChange event.

The event handlers take an argument "Target As Range", so you can check if the range that's changing includes the cell you're interested in.
