I have a 34MB excel file. How can I reduce the size of it. I have blank rows from row 110-65536 and blank columns from col V-IV which I want to delete. I tried selecting the last row, then CTRL+SHIFT +DOWNARROW followed by DEL but it doesn't seem to work since the scroll bar at the right is still tiny which means that there are endless rows below. Why can't I simply delete them.
