I'm trying to compare sheet1 "A" column values to sheet2 "E:E" column values and copy/paste the whole line of every match to sheet3. Please help me to complete this task. I'm very new to VBA.
Thank you very much in advance!
Sub DelDups_TwoLists()
Dim iListCount As Integer
Dim iCtr As Integer
' Turn off screen updating to speed up macro.
Application.ScreenUpdating = False
' Get count of records to search through (list that will be deleted).
iListCount = Sheets("sheet1").Cells(Rows.Count, "A").End(xlUp).Row
' Loop through the "master" list.
For Each x In Sheets("Sheet2").Range("E:E" & Sheets("Sheet1").Cells(Rows.Count, "A").End(xlUp).Row)
' Loop through all records in the second list.
For iCtr = iListCount To 1 Step -1
' Do comparison of next record.
' To specify a different column, change 1 to the column number.
If x.Value = Sheets("Sheet1").Cells(iCtr, 1).Value Then
' If match is true then delete row.
Sheets("Sheet1").Cells(iCtr, 1).EntireRow.Copy
Sheets("Sheet3").Select.Paste
End If
Next iCtr
Next
Application.ScreenUpdating = True
MsgBox "Done!"
End Sub
Sub DelDupsTwoLists()
Dim lastRowWs1 As Long, lastRowWs2 As Long
Dim ws1 As Worksheet, ws2 As Worksheet, ws3 As Worksheet
Set ws1 = Worksheets(1)
Set ws2 = Worksheets(2)
Set ws3 = Worksheets(3)
lastRowWs1 = LastRow(ws1.Name, 1)
lastRowWs2 = LastRow(ws2.Name, 5) 'E = 5
Dim myCell1 As Range, myCell2 As Range
Dim ws1Range As Range, ws2Range As Range
Set ws1Range = ws1.Range(ws1.Cells(1, "A"), ws1.Cells(lastRowWs1, 1))
Set ws2Range = ws2.Range(ws2.Cells(1, "E"), ws2.Cells(lastRowWs2, 1))
Dim rangeToDelete As Range
For Each myCell1 In ws1Range
For Each myCell2 In ws2Range
If myCell1.Value = myCell2.Value Then
Dim lastRowWs3: lastRowWs3 = LastRow(ws3.Name, 1) + 1
myCell2.EntireRow.Copy Destination:=ws3.Cells(lastRowWs3, 1)
If Not rangeToDelete Is Nothing Then
Set rangeToDelete = Union(rangeToDelete, myCell2.EntireRow)
Else
Set rangeToDelete = myCell2.EntireRow
End If
End If
Next
Next
If Not rangeToDelete Is Nothing Then
Debug.Print "Deleting rangeToDelete - "; rangeToDelete.Address
rangeToDelete.Delete
End If
Debug.Print "Done!"
End Sub
Public Function LastRow(wsName As String, Optional columnToCheck As Long = 1) As Long
Dim ws As Worksheet
Set ws = Worksheets(wsName)
LastRow = ws.Cells(ws.Rows.Count, columnToCheck).End(xlUp).Row
End Function
Pretty much I rewrote the whole code from scratch. It pretty much uses the initial n2
complexity, but is rather faster than that, because the deletion of the rows in WorkSheet(2)
is done in a single last step rangeToDelete.Delete
, which saves a lot of time.
Pretty much, the code defines 2 ranges with which is works - ws1Range
and ws2Range
, using the LastRow
function. Once it defines them, it starts looping through them and comparing them. Hence the n2
complexity. In case of equal values, the row is copied and the cell is added to the rangeToDelete
.
Note - it will probably not work as "out of the box solution", but try to debug further with F8 and see what happens.
Additionally:
Sub
name is used for Events in VBA, thus it is not a great idea to use it. (although it works) Give this a try (see comments in code for more details):
