You can buy software that will break just about any protection that can be
applied in Excel.

Good Day: I am wondering if anyone can tell me how I can protect a
spreadsheet (workbook) from being copied. Is there any software out there
that can be installed with the spreadsheet to lock it and require a key
code
to open.
