As we can have changes in word permanently by changing the Normal.dot file.
But in excel, is it possible to make this kind of changes.

As i have made a module (spellnumber) in one of my excel file but this
module works only within the file where it has been created.

I have to import that module in each file where i want to use this
spellnumber formula. Is there anyway that i could save this module in the
main excel program that when-ever i run excel the spellnumber should work in
it...

Thanks and Regards
