Not sure if this will help but if you are dumping csv into Excel then you could concatenate the data in the form into a single field with comma separated values and maybe copy/paste that into Excel.
You have to write the code to do this copying all the pertinent data into the field and adding commas.
field.rawValue = field1.rawValue + ", " + field2.rawValue + ", " //etc.
I think there are ways to hook into Excel using a schema but I've not done it.
