How can I open an excel file previously made from Excel?
I have all my sport's statistics saved from my old Mac using Microsoft Office 2004. When I purchased my new Retina Display I was under the impression that all my old Excel files could be opened and changed using Numbers. Unfortunately, that is not true because I cannot open any of my basketball stats (73 years worth) using Numbers. I am sure if I could open them, I could then transfer them to Numbers. Can anyone tell me what I can do? Thanks in advance.
