add a column and put this formula in the top cell:

=LEFT(A2,4)&"."&MID(A2,5,4)&"."&RIGHT(A2,4)

This assumes your data is in column A and starts in cell
A2. Drag the
formula down. Select the new column of data. Copy it
and then Paste
Special | Values back over itself. You can then copy
the data over the
original if you wish.
