As you can tell from the previous thread, there's no built-in way to read the file. You could try to find a third-party reader, or have your excel file saved as a CSV which would be easily readable.

If my reply answers your question, please mark this post as answered.
NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined
objects and unknown namespaces.
