Excel internal security is very weak.

There is nothing PA can do to ensure PB cannot make changes.

If PB is to only see but not alter the workbook, I would suggest PA sends
the workbook as a PDF file to PB and at the same time sends the workbook to
PC as an Excel file.

Document is emailed from party A, to party B and then to party C (me). I want

party B can not make any changes.

Thank You.
