I have often linked Excel worksheets and ranges to Visio over the years. I used the Database Wizard initially, but have been using the Link Data to Shapes feature since Visio 2007. I had noticed that I sometimes didn’t get a full list of the available ranges when trying to link in Visio, so I decided to investigate why.
Firstly, I created a sample Excel 2010 worksheet with a header row, and three rows of data in Sheet1.
