1.对比两行不同的数据

=IF(COUNTIF(A:A,B3),"有","")

2.汇总数据，按照类型合并数据

alt+F11进入宏录制，然后开发工具-插入-按钮选择刚录制的宏，运行即可。

Sub yy()

    Dim Arr, i&, d, Myr&

    Set d = CreateObject("Scripting.Dictionary")

    [c2:d65535].Clear

    Myr = [a65536].End(xlUp).Row

    Arr = Range("a1:c" & Myr)

    For i = 2 To UBound(Arr)

        If Not d.exists(Arr(i, 1)) Then

            d(Arr(i, 1)) = Arr(i, 2)

        Else

            d(Arr(i, 1)) = d(Arr(i, 1)) & "," & Arr(i, 2)

        End If

    Next

    k = d.keys

    t = d.items

    [c2].Resize(d.Count, 1) = Application.Transpose(k)

    [d2].Resize(d.Count, 1) = Application.Transpose(t)

End Sub

3.逗号拆分单元格中数据

=IF(ISERR(FIND(",",A2)),A2,LEFT(A2,FIND(",",A2)-1))

4.查询对应列的数据

=VLOOKUP(D2,‘6u4以下-新‘!E:J,6,FALSE)

5.删除重复数据

在 6u4探索的sheet 删掉指定的106行

Sub test()

Dim rn2, rn1 As Range

Application.ScreenUpdating = False

For Each rn2 In Sheet2.Range("a2:a5040")

  For Each rn1 In Sheet1.Range("a2:a107")

  If rn1 = rn2 Then rn1.EntireRow.Delete

    End If

    Next

  Next

  Application.ScreenUpdating = True

End Sub

方式2在 6u4探索的sheet 删掉指定的106行

Sub DelRow()
Dim arr
endrow1 = Sheet1.Range("A65536").End(xlUp).Row
endrow2 = Sheet2.Range("A65536").End(xlUp).Row
arr = Sheet2.Range("A1:A" & endrow2).Value
For i = 1 To UBound(arr)
For ii = 1 To endrow1
If Sheet1.Range("A" & ii) = arr(i, 1) Then Sheet1.Range("A" & ii).EntireRow.Delete
Next ii, i
End Sub
