Problem – Highlight a Row based on Values in the Row

I want to hi-lite a row where the value in colum k is different than the value in colum m in the specified row the value may be the same in k2 and k3 therefore duplicates does not work only if the value in the specific row are not the same it must be hi-lited and if k=m it must be removed.

I need an automated way to hi-lite these rows as the check must be done across 20,000 rows in a worksheet. Thanks for any help you can provide.

For this problem we received a sample workbook that provided the starting point. You can see in the screen shot below that the data contained a number of rows and the key columns of K and M are to be compared to determine if a row should be removed. The formatting of some rows was set as an example.

To solve this request we decided to use a macro that would run across the worksheet. It would look at the values in each column and depending on the comparison would set a value to indicate a “match” or “different” it would also set the entire row fill color.

Step 1 – Create Macro to Compare and Set Format

The following VBA macro can be copied into any module within the workbook that needs perform the compare between the values. Note that the columns to be compared can be changed by modifying the constant at the the start of the routine. For this solution we have also added a value that results from the compare to be “matched” or “different”. That value once set can be used to filter the rows that need to be deleted from the worksheet.

Open the workbook with the sheets that are to be printed and start the Visual Basic Editor (Alt + F11). Right Click in the project explorer window and select Insert > Module. Copy the following code into the new Module

Sub CheckAndHighlightRows()
'The following routine will check values

Dim myRange As Range
Dim i As Long

Const strValueOne = "K1"
Const strValueTwo = "M1"

Set myRange = ThisWorkbook.Worksheets("Sheet1").Range(strValueOne)
i = 0
Do While myRange.Offset(i, 0).Value <> ""

If IsNumeric(myRange.Offset(i, 0).Value) And IsNumeric(myRange.Offset(i, 2).Value) Then

If myRange.Offset(i, 0).Value = myRange.Offset(i, 2).Value Then
myRange.Offset(i, 3).Value = "Matched"
myRange.Offset(i, 0).EntireRow.Interior.Color = vbRed
myRange.Offset(i, 3).Value = "Different"
myRange.Offset(i, 0).EntireRow.Interior.Color = vbYellow
End If

End If

i = i + 1

End Sub

Step 2 – Running the Macro

Once the Macro is copied into your workbook you can run it from within the Code Module by selecting “Run”. You can also go back to the worskheet and select the Developer Tab > Macros > Run after selecting the macro “CheckAndHighlightRows”.

Once the Macro has run the worksheet should be updated with the relevant highlighting and the value of the comparison set to show if the values were “matched” or “different”.
