Problem is the data are imported as numbers. Since the format has 14
digits no information is lost. I don;t know of a format to hide least
significant digits of integers but you can construct a date in another
column with the following formula (assume first date in A2)

=DATE(--LEFT(A2,4),--MID(A2,5,2),--MID(A2,7,2))

Note that you can ensure that the full imported string will be
displayed with either of the following Number Formats for the dates
column:

1. You can format the column as Text.
2. You can apply a custom Number Format of "00000000000000" (i.e. 14
zeros)
