Merging Workbooks to make calculations faster

[Skittlebeanz]

My pet excel project has become 11 workbooks each with multiple sheets and running tons of calculations. Mostly if(and) or vlookups….Each change now takes up to 5 minutes to perform and I have a very fast laptop using multiple cores…..I need to speed the whole thing up so my question is, would it be faster if I merged all the workbooks together or can I do something else?

I’m loathed to rebuild the whole thing because it’s taken me 18 months of tweaking and adapting to build and finally getting some good results but starting to think it might be worth doing…..I’m open to any and all suggestions

This is your challenge...

And the only solution is to SET calculations to manual

It has got it's own risks an advantages involved - Do keep them in mind before switching. But that is the only solution, if you want to speed up...

Hi

Putting the content in one workbook could improve speed.
However you should also optimize your model.
Or put the calculations in the PQ module - so calculations will only start on request.
