Recently, my previous mentor Brian Prince asked me to take part in an ARCast presentation that highlighted some work I had done with Excel Services in SharePoint. Needless to say, I was honored to do so.
ARCastTV post on MSDN
In this video we discuss the advantages of Excel Services and some of the scenarios in which it can be used. We also touch on the OpenXML format and one of the instances in which we used this in conjunction with Excel Services to provide a comprehensive solution to a client.
It was my intention to have a blog post that discussed this procedure at length before the ARCast video went live but it would seem I am behind schedule on that issue. I still intend to publish this but if you are desperate to know the details now please send me a comment to that effect and I will make it a priority.
