Something like this:
=--if(len(a1)=4,"1/1/"&a1,if(len(a1)8,"1/"&a1,a1)

Is it possible to clean up a date field where someone was keeping an excel
sheet but the date field is a mess

For example he has
1998
2/2005
1/1/2010

We need all dates to be mm/dd/yyyy?

Is there a formula or update I could run against this so he's not going
thru
3000 rows of data?

Thank you!
