Excel-超过50万行的Vlookup公式-如何加快速度？

Question

I'm new to this forum and need your help.

I have a few tables on my report with over 500k rows in each and need to perform multiple vlookups. With the below vlookup formula it takes me forever to do so (I need to do it for the last few years, monthly).

My formula is as below:

=VLOOKUP(A:A,'Oct Corrected'!A:C,2,0)

How can I speed these calculations up? Can I use any different formula instead?

Thanks guys!

Try to use macro then add like this

Application.ScreenUpdating = False
Application.WorksheetFunction.VLookup(A:A,'Oct Corrected'!A:C,2,0)
Application.ScreenUpdating = True
