I want to Create One Report via Excel Macros

I have 3 courses that create 3 Excel worksheets that I want to combine into one worksheet. How do I do that?

Create the Macro

Export your report to Excel.
Go to View - Macros - Record Macro
Enter a name for the macro - Select a Shortcut Key - Store the macro in "Personal Macro Workbook"
Note everything after this point is memorized
When you are done - go to Macros - Stop Recording
Save the report.
Select "Save All" to the comment below

Execute the Macro

VOILA! You have just created and executed an Excel macro!
