Open and run the same Excel files simultaneously

New Contributor


I have an engineering model built in Excel 2019 which takes around 4 hours to run. 


I need to run it overnight twice at least, so I need to open the same model twice and run it. 


Is there a way I can do this?

4 hours each time? Maybe VBA from another workbook to run them consecutively?? Or you could open workbook in two instances of Excel, but I think you'll probably run into processing bottleneck if it takes 4 hours due to really intense formula re-calculation.

@tboulden yea 4 hours each time


I will try the methods you mentioned many thanks
