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!

Try this free Tool(docoptimizer.com) , it can reduce the number of styles in use and the number of activated cells.
