With all due respect, I must disagree with you. The example of a data source
at
http://www.mvps.org/dmcritchie/excel/mailmerg.htm
is not normalized. Even the Mail Merge Wizard in MS Word leads the user to
a more normalized set of fields. The example you cite combines frist and
last name and also combines city, state and zip.
The heavy mailmerge user needs much flexibility in sorting, by last name, or
city or state or someother field. They are also mainly Word users and not
power users of Excel. While sorting by State in a field of combined City,
State, Zip data would be easy for you (even I can do it). an administrative
assistant, under the gun to get out 800 form letters does not have time to
learn.
