Supervisor Hierarchy
 

I'm not sure if this possible in excel, but i have spreadsheet with 2
columns, employee names and the names of their supervisors. im trying to
create a hierarchy list starting with the president down to all the
individual employees. see example below:

Column A Column B
EE Name Sup Name
john smith bob howard
david hall bob howard
rob hodge susan parks
chris brown susan parks
susan parks tim higgs
bob howard tim higgs
tim higgs (blank)

Desired result or something comparable, perhaps in flow chart format:

tim higgs
bob howard susan parks
john smith david hall rob hodge chris
brown
