I was sent a large spreadsheet full of data and needed to check the
validity of the info in a column.

I found that an item had been input in error - instead of the actual
figure the preceeding figure had been duplicated.

I highlighted this, but before finishing the page we had a powercut and
I lost the error.

I do not really want to check the whole thing again - it took 3 hours.

Is there any way of finding duplicate, but unknown data?

Like find all references of duplicate entries?

Cheers

If the dulpicate cells are adjacent in the same column, try this macro. It
records all duplicate rows in another column. The comments should explain
it.

Sub find_dupes()
rr = 1 ' row to start recording results
rc=2 ' column to record results
c = 1 ' column to search (1=A, 2=B...)
For r = 2 To 12 ' rows to search (must start at minimum of 2)
If Cells(r, c) = Cells(r - 1, c) Then
Cells(rr, rc) = r
rr = rr + 1
End If
Next
End Sub

Good morning Philiphales

I have a free add-in available to anyone who requests it, which
contains a number of utilities. One of these will do just what you're
asking. If you want this, just drop me a line.

HTH

You could insert an adjacent column and use a formula like:

=countif(a:a,a1)
and drag down

Then apply data|filter|autofilter to that column.
Filter to show values 1.
