The spreadsheet I sent gave columns A thru AB, but some 
may not have separated exactly correct. Not knowing 
exactly what changes would be needed.
Started by inserting a row at top.


To convert date to an actual date field. In ad1 put B.
In ad2 put this formula to make a date.
=DATE(LEFT(B2,4),MID(B2,5,2),RIGHT(B2,2))
In ae1 put D
In ae2 put
=TIME(INT(D2/100),MOD(D2,100),0)
