[英]Excel Macro to delete a row if cell in Column A equals cell in Column B
Need some help here.这里需要一些帮助。 Nothing that I've searched for seems to fit my situation.我搜索的任何内容似乎都不适合我的情况。 I have a large data set where Column A and Column B have some duplicates.我有一个大数据集,其中 A 列和 B 列有一些重复项。 To clarify, it is a personnel data set with Column A being employees and column B being spouses of those employees.澄清一下,这是一个人事数据集,A 列是员工,B 列是这些员工的配偶。 However, some employees are married to each other, so I would like to delete the second instance on the list where both employees are married to each other.但是,有些员工已结婚,因此我想删除列表中两个员工都已结婚的第二个实例。 A sample of my data is this:我的数据样本是这样的:
Column A
Kim
Dave
Jim
Mary
Mike
Column B
Mike
Angela
Susan
Bob
Kim
In this case, Mike is married to Kim, which is depicted in both rows 1 and 5. I want to delete row 5. It is a rather large dataset, so doing it manually would take hours with a probability of human error.在本例中,Mike 与 Kim 结婚,这在第 1 行和第 5 行中都有描述。我想删除第 5 行。这是一个相当大的数据集,因此手动操作可能需要几个小时,并且可能会出现人为错误。 Thanks!\\谢谢!\\
Edited to include my code:编辑以包含我的代码:
Sub DeleteDuplicates()
Application.ScreenUpdating = False
'Declare variables
Dim var As Variant, iSheet As Integer, iRow As Long, iRowL As Long, bln As Boolean
'Set up the count as the number of filled rows in the first column of Sheet1.
iRowL = Cells(Rows.Count, 1).End(xlUp).Row
'Cycle through all the cells in that column:
For iRow = 2 To iRowL
'For every cell that is not empty, search through the first column in each worksheet in the
'workbook for a value that matches that cell value.
If Not IsEmpty(Cells(iRow, 2)) Then
For iSheet = ActiveSheet.Index + 1 To Worksheets.Count
bln = False
var = Application.Match(Cells(iRow, 2).Value, ActiveSheet.Columns(9), 0)
'If you find a matching value, clear the cell contents and exit the loop;
'otherwise, continue searching until you reach the end of the workbook.
If Not IsError(var) Then
bln = True
Exit For
End If
Next iSheet
End If
'If you do not find a matching value, do nothing, if you do find a matching value, clear the contents of the cell
If bln = True Then
ActiveSheet.Rows(iRow).EntireRow.Delete
End If
Next iRow
Application.ScreenUpdating = True
End Sub结束子
Put this formula in C1 (Assuming your data starts in A1 and B1) =COUNTIFS(A$1:A1,B1,B$1:B1,A1)
将此公式放在 C1 中(假设您的数据从 A1 和 B1 开始) =COUNTIFS(A$1:A1,B1,B$1:B1,A1)
Drag down拖累
Filter data to remove none 0过滤数据以删除无 0
It works using an expanding range, counting the occurrence of the flip.它使用扩展范围工作,计算翻转的发生。 An expanding range is used to stop it from counting the original ie the one you want to keep.扩大范围用于阻止它计算原件,即您想要保留的那个。
Here is my sample data and results:这是我的示例数据和结果:
Kim Mike 0
Bob Mary 0
Jim Susan 0
Mary Bob 1
Dave Angela 0
Mike Kim 1
You should be able to change this to suit your needs.您应该能够更改此设置以满足您的需求。 It compares columns A & B to look for duplicates and if found, deletes them.它比较 A 和 B 列以查找重复项,如果找到,则删除它们。 It's code I previously wrote for something else but you're welcome to see if it works for you.这是我之前为别的东西写的代码,但欢迎你看看它是否适合你。
Sub FindDuplicates()
Dim i As Long, j As Long
Dim numberOfAccounts As Long, numberOfBillClasses As Long
Dim nxtRow As Long
Dim checkForRange As Range, DupeRange As Range
numberOfAccounts = Range("B" & Rows.Count).End(xlUp).Row
esrd = Range("A" & Rows.Count).End(xlUp).Row + 1
For i = 2 To numberOfAccounts
Set checkForRange = Range("B" & i)
For j = 1 To esrd - 1
Set DupeRange = Range("A" & j)
If StrComp(CStr(checkForRange.Value), CStr(DupeRange.Value), vbTextCompare) = 0 Then
checkForRange.Interior.ColorIndex = 22
End If
Set DupeRange = Nothing
Next j
Set checkForRange = Nothing
Next i
End Sub
'This macro will delete the duplicates found after using the above macro.
Sub DeleteDuplicates()
Dim Lastrow As Long
Dim Lrow As Long
Dim CalcMode As Long
Dim ViewMode As Long
With Application
CalcMode = .Calculation
.Calculation = xlCalculationManual
.ScreenUpdating = False
End With
Lastrow = Range("B" & Rows.Count).End(xlUp).Row
For Lrow = Lastrow To 2 Step -1
If Cells(Lrow, "B").Interior.ColorIndex = 22 Then
Cells(Lrow, "B").Delete
End If
Next Lrow
'Removes color from duplicate cells
Columns("B:B").Select
With Selection.Interior
.Pattern = xlNone
.TintAndShade = 0
.PatternTintAndShade = 0
End With
End Sub
You could use this formula:你可以使用这个公式:
=IFERROR(IF(AND(SUM(($A:$A&$B:$B=A1&B1)+($B:$B&$A:$A=A1&B1))>1,ROW(INDEX($B:$B,MATCH(A1,$B:$B,0)))<ROW()),"Duplicate",""),"")
In an empty column, like column C put it in C1, confirm with Ctrl-Shift-Enter.在空列中,如 C 列将其放入 C1,按 Ctrl-Shift-Enter 确认。 Then Copy down.然后复制下来。 I t will put "Duplicate" in the second version of any matches it finds.它会将“重复”放在它找到的任何匹配项的第二个版本中。
Then sort on column C to bring "Duplicate" to the top and delete all those rows.然后在 C 列上排序以将“重复”带到顶部并删除所有这些行。
