I want to create customized ribbon on my excel sheet. I saw some of the tutorial (e.g, http://www.youtube.com/watch?v=hn3Qkp4Jw34) where they used Open XML package editor power tool for visual studio 2010 and worked on some xml configuration file to add ribbon. Hence I downloaded the tool and installed it. But when I drag and drop the excel file to the VS-2010, the file instead of opening in the VS editor it is opening in its new excel window. I tried to do same thing for a word file but still it is opening in new word window instead of opening in VS editor. Anybody could you please help me regarding this. I was using Visual Studio 2012 but then I came to know that Open XML package editor power tool for visual studio 2010 won't work for VS-2012 hence Installed VS-2010 but still getting same problem.
Thank you
