Yes, I'm sure it can be done with ActiveX. Look at my ExcelDemo:http://www.mathworks.com/matlabcentral/answers/18306-how-to-import-data-to-excel-through-matlab It shows you how to use ActiveX. I'm not exactly sure how to copy a sheet, but with my example of other Excel commands, and you looking up the proper method on the Microsoft Office Developer's web site (which you can do just as well as I can), you can do it. The Excel 2007 developer's web site ishttp://msdn.microsoft.com/en-us/library/bb242656%28office.12%29.aspx Look through that and eventually you'll find either the command to duplicate a sheet, or else you can just select a range (which my demo shows you how to do), and copy the data, then add new worksheet (again, in my demo), paste, and save the workbook (again, in my demo). Good luck.
