Need some help with Excel.

To achieve the desired functionality in Excel, you can use a VBA macro. Here's an example code that can help you accomplish this task:

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim rngBarcode As Range
    Dim rngData As Range
    Dim cell As Range
    
    ' Set the range for the barcode column (Column N)
    Set rngBarcode = Me.Range("N:N")
    
    ' Set the range for the data column (Column B)
    Set rngData = Me.Range("B:B")
    
    ' Check if the changed cell is in the barcode column
    If Not Intersect(Target, rngBarcode) Is Nothing Then
        ' Loop through each cell in the barcode column
        For Each cell In Intersect(Target, rngBarcode)
            ' Find the matching barcode in the data column
            Dim matchCell As Range
            Set matchCell = rngData.Find(cell.Value, LookIn:=xlValues, LookAt:=xlWhole)
            
            ' If a matching barcode is found, highlight the row in green and add date and time to column K
            If Not matchCell Is Nothing Then
                Dim rowNumber As Long
                rowNumber = matchCell.Row
                
                ' Highlight the row in green
                Me.Rows(rowNumber).Interior.Color = RGB(0, 255, 0)
                
                ' Add date and time to column K
                Me.Cells(rowNumber, "K").Value = Now()
            End If
        Next cell
    End If
End Sub

Here's how you can add this code to your Excel workbook:

1. Open your Excel workbook.
2. Press Alt+F11 to open the VBA Editor.
3. In the Project Explorer window, find your worksheet in which you want to implement this functionality.
4. Double-click on the worksheet name to open the code window.
5. Paste the above code into the code window.
6. Close the VBA Editor.

Now, whenever you scan a barcode in column N, the macro will check if it matches any value in column B. If a match is found, the corresponding row will be highlighted in green, and the current date and time will be added to column K of that row.

Make sure to save your workbook in a macro-enabled format (e.g., .xlsm) to keep the VBA code enabled.

Note: This code assumes that your barcode column is N and your data column is B. Modify the ranges (rngBarcode and rngData) in the code if your columns are located differently.
