Delete rows based on a column on another sheet

Perhaps.

Option Explicit

Sub DeleteRows()
Dim rng As Range
Dim rngNames As Range
Dim Res As Variant
Dim I As Long

    With Sheets("Sheet2")
        Set rngNames = .Range("A2", .Range("A" & Rows.Count).End(xlUp))
    End With

    For I = Sheets("Sheet1").Range("D" & Rows.Count).End(xlUp).Row To 2 Step -1

        Set rng = Sheets("Sheet1").Range("D" & I)

        Res = Application.Match(rng.Value, rngNames, 0)

        If IsError(Res) Then
            rng.EntireRow.Delete xlShiftUp
        End If

    Next I

End Sub

Hi,

Thanks for the reply. This appears to work but I haven't been able to confirm because my sheet is 45000 rows and it's been over 20 minutes and it's still going. Is there a more expedient method?

Thanks,

You could try disabling events, turning off screen updating and setting calculations to manual while the code runs.

Option Explicit

Sub DeleteRows()
Dim rng As Range
Dim rngNames As Range
Dim Res As Variant
Dim I As Long

    Application.ScreenUpdating = False
    Application.Calculation = xlCalculationManual
    Application.EnableEvents = False
    
    With Sheets("Sheet2")
        Set rngNames = .Range("A2", .Range("A" & Rows.Count).End(xlUp))
    End With

    For I = Sheets("Sheet1").Range("D" & Rows.Count).End(xlUp).Row To 2 Step -1

        Set rng = Sheets("Sheet1").Range("D" & I)

        Res = Application.Match(rng.Value, rngNames, 0)

        If IsError(Res) Then
            rng.EntireRow.Delete xlShiftUp
        End If

    Next I

    Application.ScreenUpdating = True
    Application.Calculation = xlCalculationAutomatic
    Application.EnableEvents = True
    
End Sub

Is the data in the attached workbook a 'real' representation of your data?

I ask because there could be other methods to speed things, eg using arrays, but they would be dependent on the actual data.

Hi,

Yes it is an accurate representation of the format. I have a few more actual "owners" and as stated my actual sheet is 45000 rows and more columns but it's doing the same thing which is comparing owners and if they don't exist, I need to delete the row. I just cut it down to 500 and inserted:

    Application.ScreenUpdating = False
    Application.Calculation = xlCalculationManual
    Application.EnableEvents = False

and it still took about 30 seconds to run. I have an i7 8GB and nothing else running. Would an array method be faster?

Thanks for your help,

but it still took

Hi,

Might help if I mention there are 17 columns, A-Q.

Thanks,
