VBA code is slow, needs optimization

Question

can anyone help optimize my code not crash my excel? I put it into 3 different macros because it freezes my excel. This was mostly done using the recorder.

Not sure if the culprit is vlookups, big data sets or just because i used the recorder mostly thus I do not have any shortcuts.

Can anyone help combine this code and make it run smoother?

Answer 1

Just to name a few.

Multiple lookups vs one

You are looking up the C2 many times (using VLOOKUP). You can substitute this with ONE lookup using MATCH() function, and use INDEX to retrieve the value.
Note: Also, consider using approximate match, if you can. Such can be only done on clean sorted data, but is waaaay faster.

Copying whole columns

Consider copying only the range with data, not whole columns.

Application.Calculation/Screenupdating

As Mat's Mug correctly pointed out, you should also consider shutting off some of excel application settings, while running the code, and turn them back on again at the end, to do the thing they do just ONCE.
