Copy Entire Data Set from Another Workbook

I am attempting to create a macro that will take an inactive workbook ("Workbook2") and copy all of the data from ("Sheet2") into worksheet("Sheet1") from the active worksheet.


Really not sure where to go with this. Please help me out if you understand what I am trying to do.

P.S. The Location of ("Workbook2") is : "J:\GROUPS\Heloc\Business Analysts\MSP UPFORB\Workbook2.xlsm"
