Open Source License for Excel Macros (Was: Creative Commons)

Thank you for the responses. The typical scenario for usage of the macros
would be a consultant using them to create a model and providing the results
to his client. The results would also include the open-source macro in it.
It is important that the consultant not be required to distribute their
models (in the Excel workbook) to the general public. I want to make doubly
sure that the Excel workbook is not considered derivative work of the macro
or corresponding source.

Here is the template I am considering, using GPL v3:

If you modify this Program, or any covered work, by linking or combining it
with *libraries provided in *Microsoft Excel (or a modified version of those
libraries), containing parts covered by the terms of the *Microsoft End-User
License Agreement*, the licensors of this Program grant you additional
permission to convey the resulting work. {Corresponding Source for a
non-source form of such a combination shall include the source code for the
parts of Microsoft Excel used as well as that of the covered work.}
I will also give the option of LGPL to those who don't mind their libraries
being used in closed systems, but for those who would like to prevent such
usage, I want to make sure I interpret the terms of the GPL appropriately.
Unfortunately, IANAL, and I appreciate all the guidance I have been
receiving thus far.*

recipient has the rights to do what you want them to be able to, and this
should include file format shifting.
I am assuming that nothing in the Creative Commons licensing prevents
changing of the file format, and I don't need to explicitly mention it

Thank you so much.
