For your 10.12.05 guys, using a temporary helper column
enter:
=DATE("20"&RIGHT(A6,2),LEFT(A6,FIND(".",A6)-1),MID(A6,FIND(".",A6)+1,2))

Present Drawbacks (above) are
1) Assumes all years to be 2000+
2) 2 digit months (not singles (1-9))

FWIW,

Hi,

I have a CSV file containing names, addresses, dates etc. Unfortunately
the dates have been entered in different formats eg. 10/11/2005, 25th may
2005 and 10.12.05. Is there a way of automatically changing them to
dd/mm/yyyy? The majority are in the format dd.mm.yy and at the very least
I would like to be able to change them to dd/mm/yyyy. There are about 4000
records so doing it manually is not an option.

Many thanks.
