Thanks, now I understand what you want to do.
I don't know if there is a way to access the Excel object model from Java. When I did a search for "Excel API Java," all I came up with was something called "JExcelAPI", at http://sourceforge.net/projects/jexcelapi/. Unfortunately, that's an older project that supports only Excel 2003 and earlier, so it won't be of much use for Excel 2007. NodeXL uses the workbook format introduced by Excel 2007.
That doesn't mean there isn't something more recent out there; I just haven't found it.
If it ends up that Java won't work, then C# or Visual Basic .NET might be the way to go.
