I am using Excel 2003 and I am trying to cleanup several mailing lists of name, address, city, state, zip, telephone etc.

Most of the the lists are in XLS format, however, several are in XML format.

How to I convert XML to XLS so that I can continue working on the list?

Is there a shareware conversion tool available? Or does Microsoft office a
conversion tool? I'm reluctant to download shareware.

Thanks.
