Sean,
I don't quite follow what you want to do. Did you want to update the
Excel file and have it propagate changes to the Visio diagram? I have a
product that generates flowcharts within Excel based upon the text
entered, but I'm not sure that it would be a good fit since the
flowchart generated would be created with MS Office AutoShapes.
