Have 2 lists of alpha/numeric part nos and would like to put duplicates in a 3rd column. Then we could id those part nos that are not dupes. Col A is 1st data set & col C is compare data set.
Tried using VBA from MS forum, works on field of 5 data sets. Tried on 1600 data sets, will not work:
Dim CompareRange As Variant, x As Variant, y As Variant
' Set CompareRange equal to the range to which you will
' compare the selection.
Set CompareRange = Range("C1:C1600")
' Loop through each cell in the selection and compare it to
' each cell in CompareRange.
For Each x In Selection
For Each y In CompareRange
If x = y Then x.Offset(0, 1) = x
Select range: A1:A1600
Run tools > macro > find_matches
Results of matches s/be in col B
Using Excel 2003, can use 2007 on another computer.
