I made a template for running some statistical data through. It ran slow
every time I tried saving and it wasn't until I tried e-mailing it that I
realized it was 75MB. It has 14 spreadsheets and all my data is contained
with in the first 20 columns and first 50 rows. the problem is that the rows
go down to ~65,000 and I can't seem to get rid of them. Selecting them alone
using ctl+shft+down makes the program not respond for a few minutes and when
I right click and select delete the program freezes altogether. I have tried
selecting smaller portions of the spreadsheets and it still doesn't seem to
lower the total amount of rows.

The spreadsheets were originally made in 2002 and now in 2007[Compatibility
Mode].

Any help would be much appreciated - especially considering I have people
waiting for this data, but cannot send it out.
