You don't even need to change the extention.  Many ZIP file utilities let you open regardless 
of the extension.  ( I just right click on a .xlsx file and select 7Zip - Open from my explorer 
menu.)

I've done this occassionally.  If you need to check the number of sheets and the sheet names 
(and possibly rename sheets) in a load of workbooks, the simplest way is to open the  
archive  7Zip and edit the file Workbook.xml.     

It's fairly simple to write a small utility to do this this sort of thing for all the files in a directory.
:)
