Thank you very much. Our consultant is also contacting us directly to resolve the issue as well. After further investigation, we noticed that my excel direct is exporting to "CSV" file instead of "xlsx" and that's probably what causes the export to go wrong.

It also only happens to my particular work station. I logged into another PC with my remote access and can excel direct to "xlsx" just fine.

Our consultant probably has a solution for this seemingly very simple problem. Just want to update in case someone else has the same problem. Thanks again for all your help.
