RE: Macros
Hello Caroline
Thank you for your question
This depends on what you are trying to do. Some things can be done with formulas, but when these things are too complicated for the standard set of formulas then macros can be used. It may be that you will write your own set of macros to perform a task in excel. You can also use the record macro button which will record everything you do as a macro until you click the stop button. You can then attach that marco to an excel button and each time the button is pressed, the same macro will be performed. There are a certain number of standard macros such as save sheet etc which can be used.
