My file size is 700 KB for a spreadsheet with little text and few
formulas with links but no macros. I deleted the cells to the right
and bottom of the cells being used and the size stays the same; even
deleting all of the cells in the workbook does not change the size. I
cut the spreadsheet and pasted into a new file and the new file has
the same size as the original. Any ideas? Thanks!

Delete the Rows or Columns that are empty and save voila. Do not delete just the cells but the rows or columns
