Writing to multiple sheets in Excel

Hi All,

I'm just settling into Mathcad 15. I use Excel a lot along with Mathcad and I need to transfer data back and forth between these two applications so the ability to work with Excel 2007 is a good thing for me. The data files I read into Mathcad are usually CSV files and have a lot of parameters. I load the CSV files into Mathcad then I use Mathcad to clean up the data and perform some manipulation. The finished product is a nested matrix containing matrices of the cleaned up parameters. Each parameter is a 2 column matrix containing time and the parameter data. The reason I use a nested matrix is that each parameter has a different timebase. The problem comes when I want to output the cleaned up data from Mathcad. The only thing I can do now is write CSV files, one for each parameter but with a lot of parameters (which is usually the case) I end up with a lot of CSV files, which is inconvenient.

I want to be able to write the cleaned up parameters back to Excel but in a single file with multiple sheets each labelled with the parameter name. I've looked through the help files and can't see anything that does this. Does anybody know how I can do this?
