This code is not very useful because I can put the formula directly in the sheet so why I need a macro to do it ? Depending of the purpose, I needed to delete and put back the formula each time I open my daily report for instance. Doing it manually, it is quite painful.
When I use the macro ?
Each time that I need to delete the formula and put it back.

Copy the code below and paste it into your macro. You will see my comments in green if exist so follow the help to adapt to your need.
' change formula by yours, take in account that "" should be """" ie =IF(C2=0,"empty",C2) will be =IF(C2=0,""empty"",C2)
Range("B1:B2").Formula = "your formula"
