How do I transfer Microsoft Outlook Contact 2010 files from my PC to my MacBook Air iOS operating system?

While attempting to eliminate duplicate entries on my MacBook Air Contacts file I somehow, instead, rolled all 962 contacts into a SINGLE contact! I figured the easiest way to solve the issue was to send a copy of my Microsof Outlook 2010 contacts to one of my personal email addresses. Not so luckly. I have tried to save the files to be transferred in CSV format, Tab-separated, and Excel...all to no avail. My Mac keeps telling me I have transferred the files in a non-readable file format.
