    How can I restrict the user to select only a docx file for upload and to catch it if it’s not?

    Hello John,

    You can set the AllowedFileExtensions property to the desired file types.Then use CustomValidator, either from client side or server side, for checking the file extensions.

    Here is the documentation which explains the same.
