I would do a search and replace as follows:

Highlight the cell range with the numbers that you want to convert to dates.
Open the search and replace dialogue.

Make sure that ”Regular expressions” is checked (you need to press the
”More options” button first).

Search for:
^([:digit:]{4})([:digit:]{2})([:digit:]{2})$

Replace with:
$1-$2-$3
or
$1/$2/$3
or
$3/$2/$1
or whatever format you'd prefer.

Hit ”Replace all” or search and replace them one by one.

I just tested this on my system (language=Swedish, country=Sweden). I
entered 20110729 in one cell and then replaced
^([:digit:]{4})([:digit:]{2})([:digit:]{2})$ by $1-$2-$3.
The cell displayed 11-07-29 (since the default date format on my
system seems to be YY-MM-DD) and in the formula field I could read
2011-07-29, as expected.
