Hi I have a big dataset and each item needs to be classified as either
"active" or "inactive". By default lines are inactive, unless they are
contained within a subset that is listed in a separate database, where
individual lines are classified active/inactive, in which case they are
classifed the same as the separate database.
I'm currently using the following formula in my classification column:
IF(ISNA(VLOOKUP(A1,[Active
Analysis]Data!A:Z,26,FALSE)),"Inactive",VLOOKUP(A1,[Active
Analysis]Data!A:Z,26,FALSE))
My question is, when I use this formula does Excel execute the same lookup
twice, or is it smart enough to do the lookup once and use the result twice?
Either way it certainly seems to take a long time. Is there a more
efficient method?
Thanks
