Split Start End date into multiple years

Hi All,

I am looking for a solution/VBA macro that splits start-end date into years.

So for example:
Customer Start End
Customer1 1/01/2012 31/12/2014
Customer2 1/08/2015 31/07/2017
Customer3 1/01/2014 30/06/2017


Should become:

Customer Start End
Customer1 1/01/2012 31/12/2012
Customer1 1/01/2013 31/12/2013
Customer1 1/01/2014 31/12/2014
Customer2 1/08/2015 31/12/2015
Customer2 1/01/2016 31/12/2016
Customer2 1/01/2017 31/07/2017
Customer3 1/01/2014 31/12/2014
Customer3 1/01/2015 31/12/2015
Customer3 1/01/2016 31/12/2016
Customer3 1/01/2017 30/06/2017


I would be very thankful if someone could help me out with my problem.
