Brilliant piece of work. I needed something to bridge the gap between a report generator and Graphviz. Before I started to write something I did a quick search and found this. I gave it a try and was pleasantly surprised to find that it worked and even more importantly, it had commercial quality documentation. It abstracts the interface to Graphviz in such a way as to make it much easier to use than "raw" dot syntax. I was really surprised to see the low number of downloads. Highly recommended if you need to create Graphviz diagrams.

Indeed when you need to visualize the business data to headquarters, can't find something better than this tool.

Tested the product on so may different combinations, work flawlessly in every instance. Very impressive, now works with Excel 2007, 2010 and 2013 - Make sure you download the latest version (20/5/2017). Must be one of the best excel macro driven spreadsheets I've come across.

This is without a doubt one of the best Excel tools ever created, in my opinion. The documentation, the forethought, the ease of use - not only is it incredibly easy to create Graphviz files with this tool, but it's a great segway into the DOT language and Graphviz in general. So powerful because it's so easy to use. If you have a need for Graphviz, but are unsure how to develop with it, this tool will make your life *easy*.
