I think you can select the files you want to show him from a view. Then edit > copy. Then go to a text editor or spread sheet and edit > paste. I'm on the Mac version and that doesn't work, but I think it's supported on the windows version.
Otherwise, you can definitely make a smartlist that includes your whole library (or whatever portion you want to show him). Then do File > Export Playlist. If you export it as a CSV (comma separated values) you should then be able to import that into excel or another spreadsheet. A tip: If you limit your view to only show the information you want (like Artist, Album, etc) then tell it to use "only visible fields", then it will make the export smaller, and not include lots of other information that you might not want like filename, genre, file size, bit rate, etc, etc.
Good luck,
Brian.
