Hope everyone is well.

I have a workbook that has 2 sheets.
Sheet1 will have rows delete if Column A is not found on Sheet2 Column A. Sheet2 has around 15-20 criteria's
I tried using Autofilter but it takes some time to complete. My data is anywhere from 60k-100k rows and generally half of that needs to be deleted.

Is there a more efficient way to go about this?

Hi gd6noob,

Try this (initially on a copy of your workbook as the results cannot be undone if they're not as expected):

VBA Code: 
Option Explicit
Sub Macro1()

    'https://www.mrexcel.com/board/threads/vba-delete-row-if-not-match-list.1206925
    'Delete row from Sheet1 Col. A if the entry is not in Col. A of Sheet2

    Dim lngRowFrom As Long
    Dim objCriteria As Object
    Dim rngCell As Range, rngDelRows As Range
    
    Application.ScreenUpdating = False
    
    lngRowFrom = 2 'Starting row for Sheet1 and Sheet2. Change to suit if necessary.

    Set objCriteria = CreateObject("Scripting.Dictionary")
    
    For Each rngCell In Sheet2.Range("A" & lngRowFrom & ":A" & Sheet2.Range("A" & Rows.Count).End(xlUp).Row)
        If Len(rngCell) > 0 Then
            If objCriteria.Exists(CStr(StrConv(rngCell.Value, vbUpperCase))) = False Then
                objCriteria.Add CStr(StrConv(rngCell.Value, vbUpperCase)), rngCell.Row
            End If
        End If
    Next rngCell
    
    For Each rngCell In Sheet1.Range("A" & lngRowFrom & ":A" & Sheet1.Range("A" & Rows.Count).End(xlUp).Row)
        If objCriteria.Exists(CStr(StrConv(rngCell.Value, vbUpperCase))) = False Then
            If rngDelRows Is Nothing Then
                Set rngDelRows = Sheet1.Rows(rngCell.Row)
            Else
                Set rngDelRows = Union(rngDelRows, Sheet1.Rows(rngCell.Row))
            End If
        End If
    Next rngCell
    
    Set objCriteria = Nothing
    
    If Not rngDelRows Is Nothing Then
        rngDelRows.EntireRow.Delete
        MsgBox "All items in Col. A of Sheet1 that were not in Col. A of Sheet2 have now been deleted.", vbInformation
    Else
        MsgBox "There were no records found in Col. A of Sheet1 that were not in Col. of Sheet2.", vbInformation
    End If
    
    Application.ScreenUpdating = True
        
End Sub

Thanks for the quick response.
I don't know if it's just me but when I ran this on my large dataset, it seems to just crash my workbook.

That's odd as it worked for me :confused:

I did reference the tabs using their assumed code names so maybe that's issue so see how this goes:

VBA Code: 
Option Explicit
Sub Macro1()

    'https://www.mrexcel.com/board/threads/vba-delete-row-if-not-match-list.1206925
    'Delete row from Sheet1 Col. A if the entry is not in Col. A of Sheet2

    Dim lngRowFrom As Long
    Dim objCriteria As Object
    Dim rngCell As Range, rngDelRows As Range
    
    Application.ScreenUpdating = False
    
    lngRowFrom = 2 'Starting row for Sheet1 and Sheet2. Change to suit if necessary.

    Set objCriteria = CreateObject("Scripting.Dictionary")
    
    For Each rngCell In Sheets("Sheet2").Range("A" & lngRowFrom & ":A" & Sheets("Sheet2").Range("A" & Rows.Count).End(xlUp).Row)
        If Len(rngCell) > 0 Then
            If objCriteria.Exists(CStr(StrConv(rngCell.Value, vbUpperCase))) = False Then
                objCriteria.Add CStr(StrConv(rngCell.Value, vbUpperCase)), rngCell.Row
            End If
        End If
    Next rngCell
    
    For Each rngCell In Sheets("Sheet1").Range("A" & lngRowFrom & ":A" & Sheets("Sheet1").Range("A" & Rows.Count).End(xlUp).Row)
        If objCriteria.Exists(CStr(StrConv(rngCell.Value, vbUpperCase))) = False Then
            If rngDelRows Is Nothing Then
                Set rngDelRows = Sheet1.Rows(rngCell.Row)
            Else
                Set rngDelRows = Union(rngDelRows, Sheets("Sheet1").Rows(rngCell.Row))
            End If
        End If
    Next rngCell
    
    Set objCriteria = Nothing
    
    Application.ScreenUpdating = True
    
    If Not rngDelRows Is Nothing Then
        rngDelRows.EntireRow.Delete
        MsgBox "All items in Col. A of Sheet1 that were not in Col. A of Sheet2 have now been deleted.", vbInformation

Another option?

VBA Code: 
Option Explicit
Sub gd6noob()
    Application.ScreenUpdating = False
    Application.Calculation = xlManual
    Dim ws1 As Worksheet, ws2 As Worksheet
    Set ws1 = Worksheets("Sheet1")
    Set ws2 = Worksheets("Sheet2")
    
    Dim lr As Long, lc As Long, i As Long, j As Long
    lr = ws1.Cells(Rows.Count, 1).End(3).Row
    lc = ws1.Cells(1, Columns.Count).End(xlToLeft).Column + 1
    
    Dim arr
    arr = ws2.Range("A2", ws2.Cells(Rows.Count, "A").End(xlUp))
    arr = Application.Transpose(Application.Index(arr, 0, 1))
    
    With ws1.Range("A1")
        .AutoFilter 1, Array(arr), 7
        ws1.Range(ws1.Cells(2, lc), ws1.Cells(lr, lc)).SpecialCells(12).Value = 1
        .AutoFilter
    End With
    
    ws1.Range(ws1.Cells(2, 1), ws1.Cells(lr, lc)).Sort Key1:=ws1.Cells(2, lc), order1:=1, Header:=2
    
    i = WorksheetFunction.Sum(Columns(lc))
    j = i + 2
    
    If i > 0 Then ws1.Range("A" & j & ":A" & lr).EntireRow.Delete
    ws1.Columns(lc).ClearContents
    Application.ScreenUpdating = True
    Application.Calculation = xlAutomatic
End Sub

Another one to test with a copy of your workbook.
I have assumed that both sheets have a header row with actual data starting on row 2.

VBA Code: 
Sub Del_Rws()
  Dim d As Object
  Dim a As Variant, b As Variant
  Dim nc As Long, i As Long, k As Long
 
  Set d = CreateObject("Scripting.Dictionary")
  With Sheets("Sheet2")
    a = .Range("A2", .Range("A" & Rows.Count).End(xlUp)).Value
  End With
  For i = 1 To UBound(a)
    d(a(i, 1)) = 1
  Next i
  With Sheets("Sheet1")
    nc = .Cells.Find(What:="*", LookIn:=xlFormulas, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column + 1
    a = .Range("A2", .Range("A" & Rows.Count).End(xlUp)).Value
    ReDim b(1 To UBound(a), 1 To 1)
    For i = 1 To UBound(a)
      If Not d.exists(a(i, 1)) Then
        b(i, 1) = 1
        k = k + 1
      End If
    Next i
    If k > 0 Then
      Application.ScreenUpdating = False
      With .Range("A2").Resize(UBound(a), nc)
        .Columns(nc).Value = b
        .Sort Key1:=.Columns(nc), Order1:=xlAscending, Header:=xlNo
        .Resize(k).EntireRow.Delete
      End With
      Application.ScreenUpdating = True
    End If
  End With
End Sub

I was able to finally get it work, my initial dataset had about 60k rows which didnt work, then I reduced it to 30k and same problem. Reduced it down to 15k rows and it worked. took about a min and a half. Perhaps there is a limit on how much data it can handle?
Thank you for the help.
