    Hi Bill,

    Thank you for being part of Microsoft Community.

    • Are you referring to Microsoft Excel when you say spread sheets?
    • Did you make any changes to the computer prior to the issue?

    Please reply to the questions in order to assist you in a better way.

    Let me rephrase, how can I add a new file extension to Default Programs under "Associate a file type or protocol with a program."

    The easy way is to use File Explorer, right-click on a file with the extension you want to add and select 'Open with..'. Choose an appropriate app from the lists, or browse to find the right application. Tick the 'always open with...' box and click OK.

    The harder way is to edit the registry. This tutorial has .reg files to reset each of the standard associations. Have a look at one as a guide.

    If this new file association is something you wish to set up on multiple machines or for multiple users, then this is how to export and import your custom default associations.
