Hi guys,
thanks for your fasted replys ( Specially JEFF Meyers).
i did manage to create a workaround for my needs, this is what i did:
assuming that i have the value "May 3 2012 12:00AM" without quotes on cell A1 i have created 4 more columns , B1 for Months,C1 for Days , D1 for Years and E1 for complete date.
I had also created a table with months definitions ( Jan =1 , Fev = 2 , Marc = 3....)
then i have applied the following formulas:
B1 Months -=vlookup(Left(A1,3),Months,2,0)
C1 Days - =Left(Right(A1,15),2)*1
D1 Years - =Left(Right(A1,12);4)
E1 =(C1&"-"&B1&"-"&D1)*1 to have the format 03-05-2012.
maybe this is a huge workaround but the fact is that it´s working
thank you
