jigneshthar, Vlookup will work, too, but will be slower than Match(). Countif() is probably the fastest function for this. Does not make much of a difference in small files, but for large datasets it might pay off to use a fast function.

teylyn - I wan't aware about this. Do you know why that is? Doesn't vlookup end as soon it finds first exact match which is similar to Match loop?

Countif should be longest as it has to loop through entire column B to get the result.

Vlookup is slower because after finding the item it then needs to locate the column to return. This is another operation that cost a few nanoseconds. Match simply returns the row index.

Countif works in a completely different way and is super-fast.

teylyn - Very interesting!! Can you point me to some resources where it comparaes various functions from performance point of view?

If Vlookup is to return same column (B:B), it doesnt necessarily have to do another lookup - assuming it is smart enough. :-)

@Venurajav, sorry for the highjack. Maybe you get something out of it, too.

Some light reading. If you are interested in fast Excel, then read anything by Charles Williams.


Re Countif:
" If you cannot use two cells, use COUNTIF. It is generally faster than an exact match lookup:" source: http://msdn.microsoft.com/en-us/library/office/aa730921(v=office.12).aspx (by Charles Williams)

And a discussion among Excel MVPs about what is faster: Vlookup or Index/Match (mind you, it turns out that Vlookup is faster, but they compare it with the Index/Match COMBO, where Match is nested in an Index function, and not with a simple Match on its own.

Also, there's code to time things, so if you want to give this a go ...


cheers, teylyn

@Venurajav, sorry about barrage of posts for simple solution!! :-) Am still learning and I see there is long way to go...

@teylyn, thanks for all the resources. Will certainly going to digest so that I can write performant formula / code. Thanks again!! :-)
