On your menu bar on the top you should see: File | Edit | View | Insert |
Format | Tools | Data | Window | Help. Click on Data, then select sort...
etc. If you can see the menu bar above do one of these:

I can't find a menu command, toolbar button, or dialog box option.
The menu may not be expanded   If arrows  appear at the bottom of the menu,
the command may be available on the expanded menu. Click the arrows, and then
click the command you want. You can also double-click the menu to expand it,
or you can change the setting to display the entire set of commands for all
menus.

The toolbar may be on the same row as another toolbar   The button may not
appear on the toolbar because there isn't enough room to display all buttons.
Click More Buttons  and then click the button you want, or you can change the
setting to show all buttons on the toolbar.

The component may not be installed   Run the installer again and install the
component.

You may have a different language setting   The command or control doesn't
appear if you don't have editing enabled for the language that the command or
control applies to. You need to enable editing for the language you want to
work with. Learn about multilingual editing and proofing tools kits.

Perhaps the Microsoft Excel Viewer really is just a viewer, therefore maybe
it doesn't allow changes, in which case you may need regular Microsoft Excel
if you want to sort. And you could probably get a low-priced older version
of regular Excel on Ebay or from some other source.
