我希望了解如何使用VBA宏删除所有重复行(当第一列中存在重复项时)。

目前Excel宏删除第一个实例的所有重复实例EXCEPT,这完全不是我想要的。我想绝对删除。

为早上快速训练做了一点点简化的解决方案:

Sub quicker_Option()

    Dim toDel(), i As Long
    Dim RNG As Range, Cell As Long
    Set RNG = Range("a1:a19") 'set your range here

    For Cell = 1 To RNG.Cells.Count
        If Application.CountIf(RNG, RNG(Cell)) > 1 Then
            ReDim Preserve toDel(i)
            toDel(i) = RNG(Cell).Address
            i = i + 1
        End If
    Next
    For i = UBound(toDel) To LBound(toDel) Step -1
        Range(toDel(i)).EntireRow.Delete

    Next i

End Sub

存储第一个实例的单元格以便以后删除。 然后去删除重复项直到结束。

Dim F as integer, S as integer   'indices for First and Second cells to be compared
Dim Deleted as boolean         'indicates if second line was deleted
Dim First as Range, Second as Range   'First and second cells to be compared
Dim Start as string                   'Indicates the position of the first cell's start

Start = "A1"   'can be as you like
Set First = Sheet1.Range(Start)  'Sets the start cell

F = 0          '
Do While First.Value <> ""    'loop while sheet contains data in the column 
    S = F + 1                 'second cell is at least 1 cell below first cell
    Deleted = false           'no second cell was deleted yet
    Set Second = First.Offset(S,0)      'second cell is an offset of the first cell

    Do While Second.Value <> ""       'loop while second cell is in sheet's range with data
        if Second.Value = First.Value then    'if values are duplicade
            Second.EntreRow.Delete              'delete second cell
            Deleted = true                       'stores deleted information
        else                                'if not, second cell index goes next
            S = S + 1;
        end if

        Set Second = First.Offset(S, 0)      'sets second cell again (if deleted, same position, if not deleted, next position
    Loop

    if Deleted then         'if deleted, should delete first cell as well
        First.EntireRow.Delete
    else
        F = F + 1           'if no duplicates found, first cell goes next
    end if

    Set First = Sheet1.Range(Start).Offset(F,0)     'sets first cell again (if deleted, same position, if not, next)
Loop

我正在使用此代码创建总帐控制帐户的自动对帐,其中如果任何具有相同值但符号相反的单元格被切割为工作表2;因此只留下了对帐项目。

代码:

sub    autoRecs()
dim i as long
Application.ScreenUpdating = False
Application.StatusBar = True
Dim i As Long
Cells(5, 6).Select
Dim x As Long
Dim y As Long
x = ActiveCell.Row
y = x + 1
Do Until Cells(x, 6) = 0
Do Until Cells(y, 6) = 0
Application.StatusBar = "Hey Relax! You can rely on me......"
If Cells(x, 6) = Cells(y, 6) * -1 Then
Cells(x, 6).EntireRow.Cut (Worksheets(2).Cells(x, 6).EntireRow)
Cells(y, 6).EntireRow.Cut (Worksheets(2).Cells(y, 6).EntireRow)
Cells(x, 6).Value = "=today()"
Cells(y, 6).Value = "=today()"
Else
y = y + 1
End If
Loop
x = x + 1
y = x + 1
Loop
Application.StatusBar = False
End Sub

Sub deleteBlankCells()`this is to delete unnecessary cells after run the above macro`
Range(Cells(5, 1), Cells(Rows.Count, 1).End(xlUp)).Select
For i = Selection.Rows.Count To 1 Step -1 
Application.StatusBar = "OOH! I'm cleaning all the blanks for you....."
If WorksheetFunction.CountA(Selection.Rows(i)) = 0 Then
Selection.Rows(i).EntireRow.Delete
End If
Next i
Application.StatusBar = False
End Sub

我喜欢在VBA中使用数组,所以这是一个例子。

  • 假设数据代表A1周围的当前区域,但很容易更改
  • 将源数据读入数组
  • 检查第一列中的每个项目以确保它是唯一的(该项目的标识= 1)
  • 如果是唯一的,请将相应的行号添加到集合
  • 使用集合的大小和列数来淡化结果数组。
  • 循环访问集合,将相应的行写入结果数组。
  • 将结果数组写入工作表。

如上所述,结果位于源数据的右侧,但也可以替换它,或者放在不同的工作表上。

Option Explicit
Sub RemoveDuplicatedRows()
    Dim vSrc As Variant, vRes() As Variant
    Dim rSrc As Range, rRes As Range
    Dim colUniqueRows As Collection
    Dim I As Long, J As Long

'assume data starts in A1 and represented by currentregion
Set rSrc = Range("a1").CurrentRegion
vSrc = rSrc

Set rRes = rSrc.Offset(0, UBound(vSrc, 2) + 2)

'get collection of non-duplicated rows
Set colUniqueRows = New Collection
For I = 1 To UBound(vSrc)
    If WorksheetFunction.CountIf(rSrc.Columns(1), vSrc(I, 1)) = 1 Then _
        colUniqueRows.Add I
Next I

'Make up results array
ReDim vRes(1 To colUniqueRows.Count, 1 To UBound(vSrc, 2))
For I = 1 To UBound(vRes, 1)
    For J = 1 To UBound(vSrc, 2)
        vRes(I, J) = vSrc(colUniqueRows(I), J)
    Next J
Next I

rRes.EntireColumn.Clear
rRes.Resize(UBound(vRes)) = vRes

End Sub
