|Thanks for your response. I already looked at this and this is way over my technical expertise. I am basically an UNIX programmer and I am just looking for some kind of a freeware utility or a service that can convert the .xla addin to COM addin.|
Or, if there is a freeware alternative to Microsoft excel that supports .XLA addin, that would be fine too. I tried couple of them like open office, liber office, kingsoft office, softmaker office suite and they don't support .XLA addin.
