I have two columns with strings of data as such:

Column A Column B

2008SPX850OCT0P2103 2008SPX850OCT0P2303
2008SPX855DEC0P208 2008SPX855DEC0P120
2008SPX855DEC-208C0 2008SPX855DEC-120C0
2008SPX1020DEC0P1022 2008SPX1020DEC0P1038

Is it possible to insert a space or comma between each number and text? I
need to keep the minus sign(-) with the number that comes after it.
e.g.
Column A Column B

2008,SPX,850,OCT,0,P,2103 2008,SPX,850,OCT,0,P,2303
2008,SPX,855,DEC,0,P,208 2008,SPX,855,DEC,0,P,120
2008,SPX,855,DEC,-208,C,0 2008,SPX,855,DEC,-120,C,0
2008,SPX,1020,DEC,0,P,1022 2008,SPX,1020,DEC,0,P,1038

Thanks for any help.
