示例 1:删除单个列表中的重复项
下面的示例宏搜索 A1:A100 范围内的单个列表,并删除列表中的所有重复项。 此宏要求列表范围内没有空单元格。 如果列表中确实包含空单元格,请按升序对数据进行排序,以便空单元格全部位于列表的末尾。
Sub DelDups_OneList()
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.
iListCount = Sheets("Sheet1").Range("A1:A100").Rows.Count
Sheets("Sheet1").Range("A1").Select
' Loop until end of records.
Do Until ActiveCell = ""
' Loop through records.
For iCtr = 1 To iListCount
' Don't compare against yourself.
' To specify a different column, change 1 to the column number.
If ActiveCell.Row Sheets("Sheet1").Cells(iCtr, 1).Row Then
' Do comparison of next record.
If ActiveCell.Value = Sheets("Sheet1").Cells(iCtr, 1).Value Then
' If match is true then delete row.
Sheets("Sheet1").Cells(iCtr, 1).Delete xlShiftUp
' Increment counter to account for deleted row.
iCtr = iCtr + 1
End If
End If
Next iCtr
' Go to next record.
ActiveCell.Offset(1, 0).Select
Loop
Application.ScreenUpdating = True
MsgBox "Done!"
End Sub
示例 2:比较两个列表并删除重复项
下面的示例宏将一个 (主) 列表与另一个列表进行比较,并删除主列表中第二个列表中的重复项。 第一个列表位于 Sheet1 中的 A1:A10 范围内。 第二个列表位于 Sheet2 中的 A1:A100 范围内。 若要使用宏,请选择任一工作表,然后运行宏。
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("sheet2").Range("A1:A100").Rows.Count
' Loop through the "master" list.
For Each x In Sheets("Sheet1").Range("A1:A10")
' Loop through all records in the second list.
For iCtr = 1 To iListCount
' Do comparison of next record.
' To specify a different column, change 1 to the column number.
If x.Value = Sheets("Sheet2").Cells(iCtr, 1).Value Then
' If match is true then delete row.
Sheets("Sheet2").Cells(iCtr, 1).Delete xlShiftUp
' Increment counter to account for deleted row.
iCtr = iCtr + 1
End If
Next iCtr
Next
Application.ScreenUpdating = True
MsgBox "Done!"
End Sub
