I have a sheet i'm working on as follows for an automotive inventory

Column A Column B
1953 1959
1953 1956
1962 1969

I need to combine the 2 columns and fill in the years between so I'd end up with a column as follows
Column A
1953,1954,1955,1956,1957,1958,1959
1953,1954,1955,1956
1962,1963,1964,1965,1966,1967,1968,1969

Is there a way to do this?
