The most likely starting point would be node_import:
http://www.drupal.org/project/node_import
It will not handle Excel files natively however--you will need to have them available as CSV files.
If that is not possible for what ever reason, you may look into a tool which converts between the formats (there are a few ways to do this in the unix world, including one direct xls2csv program, although I do not know what package it is a part of).
