Creating an XLS file from scratch

[weblyceum]

I am in the midst of designing a client-side hta application (using javascript only). I'd like to be able to create an xls file from scratch using the Scripting.FileSystemObject"). So basically, the output will be wrote to a file and saved as a .xls format.How do you do this, I also wish to stay away from the ActiveX.Object("Excel.Application). As I don't want the hta application to be dependant on the users computer.Thanks for all your help in advance,Cheers,Jay
