Loop and highlight

Hi,

I need a piece of code that counts Col A as its reference for how many rows to loop through and then starts looping down.

If it finds that there are rows which have the same value in both columns F&G, then it will highlight those rows red

I have attached a spreadsheet which shows what i would like the ss to look like after the code has ran

Thanks

Hi, Seamus.

This could be done with Conditional Formatting. Beside simplicity, the main advantage is that the highlighting would be automatically updated if either of the values changed,

Interested?

Brian.

Yep!

Seamus,

My mistake - I didn't check your file adequately. I had thought you were looking to highlight individual rows where columns F and G were the same.

You're actual requirements can be done by Conditional Formatting, but I'd be concerned that there would be an excessive processing overhead. How many rows will you have and how volatile will the data be?

Finally, by counting column A as the reference, do you mean to only include rows where column A is non-blank?

Thanks,
Brian.

There could easily be a few hundered rows of data

Yes, if Column A ends at row 75, only loop as far as 75

Thanks

Seamus,

OK, quick and dirty...

Option Explicit

Sub HighLight_Duplicates()
Dim i As Long
Dim xLast_Row As Long
Dim xLast_Col As Long
Dim xCount

Sheets("Sheet1").Activate

xLast_Col = ActiveSheet.Range("A1").SpecialCells(xlLastCell).Column
xLast_Row = ActiveSheet.Range("A1").End(xlDown).Row
If xLast_Row < 2 Then
    MsgBox ("No data found. Run cancelled.")
    Exit Sub
End If

Range(Cells(2, 1), Cells(xLast_Row, xLast_Col)).Interior.Color = 16777215

Range(Cells(2, xLast_Col + 1), Cells(xLast_Row, xLast_Col + 1)).Formula = "=F2&"":""&G2"
Range(Cells(2, xLast_Col + 2), Cells(xLast_Row, xLast_Col + 2)).Formula = "=IF(A2="""","""",COUNTIF($M$2:$M$" & xLast_Row & ",M2))"

For i = 2 To xLast_Row
    If Cells(i, xLast_Col + 2) <> 1 Then Range(Cells(i, 1), Cells(i, xLast_Col)).Interior.Color = 255
Next

Range(Cells(2, xLast_Col + 1), Cells(2, xLast_Col + 2)).EntireColumn.Delete
                   
End Sub

Hi,

Can someone explain this?

Range(Cells(2, 1), Cells(ActiveSheet.Range("A1").SpecialCells(xlLastCell).Row, xLast_Col)).Interior.Color = 16777215

&

Range(Cells(2, xLast_Col + 1), Cells(2, xLast_Col + 2)).EntireColumn.Delete

Why do you need above lines?

Thanks,
Ashok

Hi, Ashok.

(1) This is to remove any existing highlighting as the user may wish to re-run the macro after changing/deleting some rows.

(2) The main work is done by the formulas in the two new columns. Once the formatting has been applied they're no longer needed and so they're deleted.

Regards,
Brian.

Brian,

Now it makes sense.

Thank you
