Each month I download data from several testers we have on our production floor. I do my normal data crunching but have to endure having to delete empty columns manually. I can have over 400 columns and about 20-30% are always empty. Sometimes the empty column is by itself and other times I can have 2-4 columns side-by-side with no data in them. I want to delete all columns which have no data. Thanks.
