Make your excel lookups 100 times faster using Match

This method is almost instant (using 500,000 record lookups)

IF(M56=INDEX(‘Sitemap Keyword Categories’!$G$1:$G$300016,MATCH(M56,’Sitemap Keyword Categories’!$G$1:$G$300016,1),1),”Supported”,”Not Supported”)

This does an “nearest match” (using status “1”) and then tests to see if the nearest match is correct (ie “M56=”).

This Updated 500,000 records in under 1 second – previous methods (exact match using “0” and vlookup function ) would take 5 minutes.

It is vital that the column G in “Sitemap Keyword Categories” is sorted A-Z
