Hi. I need a code please that when it is run a matching set of cells are highlighted when there is data missing amongst group of rows. Below should explain better.

Column C Column AA
AUA618 2012Please Obtain OE Number And Cross Refer
AUA618 2012Please Obtain OE Number And Cross Refer
AUA618 2012Please Obtain OE Number And Cross Refer

As you can see sets of rows match in column C, if there is data missing in column AA then the rows need to be highlighted like below. You'll notice data is missing in most rows as 'Please Obtain OE Number And Cross Refer' is missing in most. The bottom set of 3 remain unhighlighted as data is in all three rows in Column AA. Thanks

I was going to suggest cf based on =AA1 = ""
Can you explain why the more complicated expression would be better, assuming it is?
Thanks.

Thanks but I really need a macro to put in my personal macro workbook. I will use on hundreds of files of different sizes with thousands of rows and also can't use helper columns.

maybe as a start (because I have to run out and can't modify to suit a personal wb right now)
VBA Code:
Sub ConditionalFormat()
    Dim ws As Worksheet
    Dim lastRow As Long, i As Integer
    Set ws = ActiveSheet

    lastRow = ws.Cells(ws.Rows.Count, "AA").End(xlUp).Row
        For i = 2 To lastRow
          If ws.Cells(i, "AA") = "" Then ws.Range("A" & i & ":" & "AA" & i).Interior.Color = vbYellow
        Next
       
End Sub

        Next
     
End Sub
Thanks but that doesn't work. Almost every row is highlighted. The code needs to look at column C first to get all the rows that match then look at column AA to see that each row has data according to the matches in C.

It is almost doing the opposite to what I want as the only unhighlighted rows are the ones with data in AA, no matter what matches in C.

Just to comment that the formula in the CF must have the sign <>
Rich (BB code):
=COUNTIF(C:C,C2)<>COUNTIFS(C:C,C2,AA:AA,"<>")

If you have thousands of records, then it might be worth using a dictionary and arrays to speed up the process.

Just to clarify, in your example data 3,4 and 5 are different than data 1,2 and 3:
1681759463280.png


The macro will start reading the data from row 1, assuming row 1 has the headers.

VBA Code:
Sub HighlightRows()      'When Data Is Missing
  Dim i As Long, y As Long, fil As Long, col As Long, j As Long, k As Long, m As Long
  Dim dic As Object
  Dim a As Variant, b As Variant, ky As Variant
  Dim bln As Boolean
  Dim rng1 As Range, rng2 As Range
 
  Set dic = CreateObject("Scripting.Dictionary")
  
  a = Range("C1:AA" & Range("C" & Rows.Count).End(3).Row).Value
  ReDim b(1 To UBound(a, 1), 1 To 1000)
 
  For i = 1 To UBound(a, 1)
    If Not dic.exists(a(i, 1)) Then
      y = y + 1
      If a(i, 25) = "" Then bln = True Else bln = False
      dic(a(i, 1)) = y & "|" & 1 & "|" & bln
      b(y, 1) = i
    Else
      fil = Split(dic(a(i, 1)), "|")(0)
      col = Split(dic(a(i, 1)), "|")(1)
      bln = Split(dic(a(i, 1)), "|")(2)
      col = col + 1
      b(fil, col) = i
      If bln = False Then
        If a(i, 25) = "" Then bln = True
      End If
      dic(a(i, 1)) = fil & "|" & col & "|" & bln
    End If
  Next
 
  Set rng1 = Range("C1,AA1")
  Set rng2 = Range("C1,AA1")
 
  For Each ky In dic.keys
    fil = Split(dic(ky), "|")(0)
    col = Split(dic(ky), "|")(1)
    bln = Split(dic(ky), "|")(2)
    If bln = True Then
      If k = 0 Then k = 1 Else k = 0
      For j = 1 To col
        m = b(fil, j)
        If k = 0 Then
          Set rng1 = Union(rng1, Range("C" & m & ",AA" & m))
        Else
          Set rng2 = Union(rng2, Range("C" & m & ",AA" & m))
        End If
      Next
    End If
  Next
 
  Range("C:C, AA:AA").Interior.ColorIndex = xlNone
  rng1.Interior.Color = vbYellow
  rng2.Interior.Color = vbBlue
  Range("C1,AA1").Interior.ColorIndex = xlNone
End Sub


The macro will also alternate colors. Example:

I think it works, but if possible if like in the example at the bottom there is data in all 3 rows (20, 21 and 22) then can they be left not highlighted? And also the same in rows 5, 6 and 7 there is no data in AA then they can be left not highlighted also? Basically I only want rows highlighted if there is an anomaly.

I thought the requirement was to highlight a row (and I took that to mean not the entire row all the way out to XFD) wherever AA was blank as below - but I guess not.

No whenever data matches in C it then needs to look at AA and if data is missing from a cell then all the rows need highlighting from A to AA
