how to export users with extended attributes to a csv file

i need to export users with their attributes created by WebLoginPE to a .cvs file which will be imported in excel.
can somebody give me suggestions?

after looking around, i found out the way to export Modx database to .csv file. thanks to http://www.modwest.com/help/kb6-135.html
this will export what you call in your query, save results in a .csv file, then open donwload file dialog for saving or viewing reason.
I put them in attached file, simple and very easy to use.
