Convert string to Date

I'm getting a tab delimited file that I need to import into an access DB. The date field comes over as an 8 character string in the yyyymmdd format.

Does anyone know an easy way to convert this to a date or a pre-existing function?

Try the built in function cdate. It should meet your needs

You might think so, but it doesn't convert this to a date. As a string, I get 'expected expression'. As a number I get 'out of range'.

I expected the number to fail, but I thought the string would work.

That's because the yyyymmdd format isn't a recognized format by Access. Strings without delimiters aren't recognized as dates.
CDate(Mid(strDa te, 5,2) & "/" & Right(strDate, 2) & "/" & Left(strDate, 4))

Yeah, I had a feeling this was the route I was going. I was just figuring there was a predefined function. Oh well, I guess I'll just write it. :)

You can happily use this that I produced a while back :

Expand|Select|Wrap|Line Numbers
  1. 'YMDToDate takes varDate in YYYYMM or YYYYMMDD format and returns it as a date.
  2. '28/01/2004 Return Null if not valid format.
  3. Public Function YMDToDate(varDate As Variant) As Variant
  4.     Dim strDMY As String
  5.  
  6.     strDMY = Mid(varDate, 5, 2) & "/" & Left(varDate, 4)
  7.     If Len(varDate) = 8 Then strDMY = Mid(varDate, 7, 2) & "/" & strDMY
  8.     YMDToDate = Null
  9.     If IsDate(strDMY) Then YMDToDate = CDate(strDMY)
  10. End Function

I'm trying to write some code that will convert any of the most popular standard date formats twice in to something like "dd Mmm yyyy" (i.e. 08 Jan 1908) and compare the first with the second and calculate days, months, and years.
