ALWAYS get your lawyer to check what you are doing is fine.
Having said that, my two cents:

That is obviously a management problem. Normally, if you are the consumer,
your provider will give you in OpenOffice if that's what you want. If you
are the provider, then you would normally have to give what your customers
I think we should not focus on the actual mechanics of the templates
delivery, i.e., Microsoft Office or OpenOffice format. The key is the
content, i.e., the arrangement of stuff you see on screen. Make sure that
recipient has the rights to do what you want them to be able to, and this
should include file format shifting.

Read up the section of "System Libraries" and the following two links from
GPL's FAQ might be of interest
IMHO but IANAL, anythings that Excel provide falls under the definition of
The second one deals with providing your own exceptions. This is the most
promising and usually the easiest to accomplish for something small like
macros where the copyrights ownership tree is not very tall and deep. One
word of advise, it is easier for your downstream developer if you get
everything in the macro GPL-ed or use a GPL compatible library for
everything in the macro except Excel-supplied functions.
