I have an excel worksheet.

Currently I'm only using 700+ rows and about 15 colums. However I could
scroll down to the 10 millionth row if I wanted. How do I get rid of all
those extra rows? Same problem with the cloumns. I basically want someone to
open up my file and see that there aren't an infinate number of rows yet to
be populated.

I found this macro that was supposed to delete all empty rows. it ran and
they were still there.
