Question : How to transpose a variable length row to two columns

I have a spreadsheet which lists AD Groups and members in a row.  I need to copy this data to another worksheet and transpose the data in two columns, Column A - Group and Column B - Member.

Current Format:
Group        Members
Group A     member1, member2, member3, member4
Group B     member1, member2, member3, member4,member5,member6
Group C     member1, member2
Group D     member1, member2, member3, member4,member5,member6,member7,member8,member9

Proposed Format:
Group A     member1
                  member2
                  member3
                  member4

Group B      member1
                  member2
                  member3
                  member4
                  member5
                  member6

Group C     member1
                  member2

Group D     member1
                  member2
                  member3
                  member4
                  member5
                  member6
                  member7
                  member8
                  member9

Thanks.
