There's nothing built into excel that allows for masks.

In fact, if you want to enter 16 digits in a cell, that cell has to be treated
as text (either preformatted as Text or entered with a leading apostrophe).

As for dates, you can use Format|Cells|Number tab and choose a nice format for
your dates--but this won't affect the way the user types the dates.
