Excel ALWAYS has 65536 rows and 256 columns, and you can't change that no
matter what you do.
However, you can hide them.
use F5 (goto). and type 750:65536, press OK, then use Ctrl/9
then use F5, type P:IV, press OK, then use ctrl/0

Now the extraneous ones are hidden from view.

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.
