Well, this is obviously not a native function of the BO, so you will need to convert the Excel document into XML and then you can use the ADO.NET DataTable command to read in the XML document and finally you can use the CopyDataFrom on the BO to bring the data in in a known format.I recommend using the MSOffice Interop classes to open and read the Excel document and dump it into an XML format. Once this is done you can bring it into a DataTable which can then be brought into the BO.
