EXCEL: highlighting reoccuring data in the same column - excel

Question

I have a column(D) of data in Excel that has been sorted using:
=TEXT(B2,"###").
This is to show a list of data (numberical) that has an additional "REP 1" against it.
Not all data has a "REP 1" in there, so I would like to highlight all fields which contain BOTH the number and the "REP 1".
I could highlight all "REP 1" fields, and see if there is a duplicate before it, but this is just a sample sheet. I have over 8,000+ fields to go through, and would be too time consuming.
Please see the below link for the example:
Required Formatting
I hope this all makes sense.
Thanks,
Tim.

Answer 1

Not sure if its possible to do with conditional formatting but this VBA code should work. Your Data wouldn't have to be sorted in any particular order, and assumes the data you are formatting is in column D. I've tested on a few 100 rows and it works fine, so should be fine with a large data set. Ive tried to explain what the code is doing through the comments in the code.
Sub formatCells()
Dim x As Variant
Dim y As Variant
Dim searchval As String
Dim a As Variant
Dim lastrow As Long
Dim rng As Range
Application.ScreenUpdating = False ' turn off screen updates
lastrow = Cells(Rows.Count, 4).End(xlUp).Row 'find the last blank cell
x = 2 'set rownumber
y = 4 'set columnnumber
While Cells(x, y) <> "" ' create loop
If InStr(Cells(x, y), "REP1") Then 'search for string in cell
Cells(x, y).Interior.Color = RGB(255, 0, 0) 'if string exists fill cell
End If
x = x + 1 ' loop
Wend ' end loop
x = 2 ' reset row number
y = 4 ' reset column number
While Cells(x, y) <> "" ' create loop 2
If Cells(x, y).Interior.Color = RGB(255, 0, 0) And InStr(Cells(x, y), "REP1") Then 'if cells is red and contains Rep1
a = Cells(x, y).Value ' set a to equal the cell that is red and and contains REP1
searchval = Left(a, Len(a) - 5) 'remove space and REP1 and set value ready for search
If searchval <> "" Then 'if theres a search value available run steps below
With Range("D1:D" & lastrow) 'set range to be column A
Set rng = .Find(What:=searchval, _
After:=.Cells(1), _
LookIn:=xlValues, _
LookAt:=xlWhole, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, _
MatchCase:=False)
If Not rng Is Nothing Then 'If search value is found
Application.Goto rng, True ' go to cell
ActiveCell.Interior.Color = RGB(255, 0, 0) 'set cell to red
End If
End With
End If
End If
x = x + 1 'loop 2
Wend ' end loop 2
End Sub
EDIT - Looks at column B not D
Sub formatCells()
Dim x As Variant
Dim y As Variant
Dim searchval As String
Dim a As Variant
Dim lastrow As Long
Dim rng As Range
Application.ScreenUpdating = False ' turn off screen updates
lastrow = Cells(Rows.Count, 2).End(xlUp).Row 'find the last blank cell
x = 2 'set rownumber
y = 2 'set columnnumber
While Cells(x, y) <> "" ' create loop
If InStr(Cells(x, y), "REP1") Then 'search for string in cell
Cells(x, y).Interior.Color = RGB(255, 0, 0) 'if string exists fill cell
End If
x = x + 1 ' loop
Wend ' end loop
x = 2 ' reset row number
y = 2 ' reset column number
While Cells(x, y) <> "" ' create loop 2
If Cells(x, y).Interior.Color = RGB(255, 0, 0) And InStr(Cells(x, y), "REP1") Then 'if cells is red and contains Rep1
a = Cells(x, y).Value ' set a to equal the cell that is red and and contains REP1
searchval = Left(a, Len(a) - 5) 'remove space and REP1 and set value ready for search
If searchval <> "" Then 'if theres a search value available run steps below
With Range("B1:B" & lastrow) 'set range to be column A
Set rng = .Find(What:=searchval, _
After:=.Cells(1), _
LookIn:=xlValues, _
LookAt:=xlWhole, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, _
MatchCase:=False)
If Not rng Is Nothing Then 'If search value is found
Application.Goto rng, True ' go to cell
ActiveCell.Interior.Color = RGB(255, 0, 0) 'set cell to red
End If
End With
End If
End If
x = x + 1 'loop 2
Wend ' end loop 2
End Sub
