What you want is Adobe PDF. We use it to 'lock' Excel sheets. Everyone can
look at the sheet but no one can change it.

If you don't have Adobe Acrobat available and don't want to buy it, you can
subscribe for a monthly fee at Adobe.com. If you won't use it enough to make
even that worthwhile, Adobe provides 5 free samples. You select the file on
your computer and Adobe will email you the file converted to PDF. You could
create a new email address at yahoo.com or hotmail.com and get 5 free
conversions for each new email address.

When I protect a workbook so that users cannot modify it without knowing the
password, what prevents the user from doing the following:
1. Open the workbook in read-only mode (I do want others to be able to read
the workbook).
2. Select save as and give the file a new name.
3. Delete the original (password protected) workbook.
4. Rename the new (unprotected workbook) to the name of the original
workbook.
5. Edit the workbook and then save the changes.
