You know you’re going to need a lot of it. Excel has a help function which you’re likely to be familiar with (“F1” when you have Excel open). VBA has its own specific help function. After you’ve got the VBA editor open (“Alt” “F11”) get used to pressing “F1” on your keyboard. That will open up VBA help. There are some other sources that you’ll find useful as well. We’ve tried to list those for you here: other helpful sources of information on macros.
