We did this directly from Excel with MS Query. If you are familiar with the use of MS Query all you need to know is:
A. How do I connect to the DBA data via ODBC?
B. Which file do I need to look in?
C. Which fields do I need for my report?
Question A should be easy for your IT person to answer for you.
Question B and C can be looked up in the (free download) file found here:

NOTE: You could also use Crystal Reports to gather the data, if that is more familiar for you.
