According to Microsoft,
"You can digitally sign any Excel workbook or Excel template. However,
Excel versions that are earlier than Microsoft Excel 2002 do not
recognize the digital signature.
If you digitally sign a shared workbook, Excel will not retain the
digital signature because more than one person can make changes to the
workbook. Additionally, you cannot code sign a macro project, because
Excel will not allow you to create or make changes to macro projects
in a workbook after it has been set up as shared workbook."
