How to Export Import vCard contacts in Outlook 2013? Does it convert multiple Contacts at once?

I am using latest edition of Microsoft Outlook 2013. I believed that it will definitely help to convert 1500 vCards contacts into Outlook 2013, all at once, but it is not supported to be possible because, still, Outlook 2013 has not improved in this direction. Any hope for me rather than exporting or importing contacts one by one???
