I have huge data set (thousand record rows) in Excel (columns -monthes, customers, expenditures). I have to find those customers who spend at least, let's say 100 USD, in **each** month. 

Is there any fast way for solution? I have tried pivot table, but without success. Maybe I should upload data set to Access then run query? Any ideas?
