Convert Date Format from yyyy-mm-dd to dd mmm yy using VBA

Hello, I am using Excel 2003 on Windows XP. Could some one please help me with a date conversion as follows:

In column F (F2:F65000) I currently have dates in yyyy-mm-dd format (e.g. 1970-04-27).

I need this date format to be changed to: dd mmm yy format (e.g. 27 Apr 70).

Please refer to my attached image showing examples of the date formats:

I can do this manually, but I have 65,000 to do.

Any assistance would be greatly appreciated,

Kind regards,

Chris
