A method for exporting contacts from iPhone which can handle more than two phone numbers per contact

I want to export my iPhone contacts to my computer. I tried to use iTunes to sync them with Windows Address Book, however, if my iPhone contact has three phone numbers, only two of them appear in WAB. I want a way to export contacts which preserves all phone numbers, their order and labels. Unfortunately, all the guides on exporting contacts that I've read don't mention limitations like this. How to do this? I don't want to put my contacts on any online service, such as Gmail or iCloud.
