Hi Betsy,
it is not posssible to open a password protected excel in the viewer.
//set the password spreadsheet1.Password = "123"; spreadsheet1.LoadFromFile("FileName");
Yet, this code only work for Excel2010, if your file is generated by Excel2013, the method would not work. I have posted the issue with Excel2013 to our Dev team. Once there is any good news, we will let you know.
