I do not believe this is possible with Spotify, or any music application for that matter. This is not a feature that is in high demand. But, as a collector, I can somewhat understand why you'd like to have it.
However, there is a work around for what you want to do. You'll have to install iTunes, and import your entire library in to iTunes. Once this is complete, you can EXPORT your library as an XML file, then IMPORT the file in to EXCEL, and manipulate your data. Just giving you fair warning, it is no easy task, because iTunes puts a lot of extraneous information into the XML file, and you'll have to clean it up first before you do anything..
