the version you've referenced in siebe's post is the massively old version of what is the current ml_impex which is shipped in Winamp. so really best to not try to even install that version (don't think it even works with current Winamp versions anyway + would overwrite the current version and undo all of the bug fixes it has had).
http://nunzioweb.com/daz/mlexporter.html has the means to dump to a csv for import into Excel if you're looking for that.
[edit]
fixed incorrect _ in the above link
