Need to combine cells where the reference is the same.
So in column A, have references which can be repeated multiple times ( number of repetition is not determinable). Need to combine the values from Column B, where the values in column A are the same.
Example has been shown below.


Original:

A B

1.1 |this is it
1.1 |there we go
1.1 |what
1.2 | what is going on
2.3 | there
4.5 |what is it


Result:

1.1 |this is it / there we go /what
1.2 | what is going on
2.3 | there
4.5 |what is it
