如何删除单元格字符串中重复的字符或单词?

作者:晓阳 最后修改时间:2020-05-19

假设每个单元格中都有重复的字符或单词,并且您要删除重复的字符并仅保留唯一的字符或单词。 您如何在Excel中解决此问题?

现在,如果您有一个文本字符串列表,则需要删除重复的字符,如下面的屏幕截图所示。 在这里,我可以谈谈处理它的VBA代码。

文档删除重复字符 1

1。 按住 ALT + F11 键打开 Microsoft Visual Basic for Applications窗口.

2。 点击 插页 > 模块,然后将以下代码粘贴到 模块窗口.

VBA代码:删除单元格中文本字符串的重复字符

Function RemoveDupes1(pWorkRng As Range) As String
'Updateby Extendoffice
Dim xValue As String
Dim xChar As String
Dim xOutValue As String
Set xDic = CreateObject("Scripting.Dictionary")
xValue = pWorkRng.Value
For i = 1 To VBA.Len(xValue)
    xChar = VBA.Mid(xValue, i, 1)
    If xDic.Exists(xChar) Then
    Else
        xDic(xChar) = ""
        xOutValue = xOutValue & xChar
    End If
Next
RemoveDupes1 = xOutValue
End Function

3。 然后保存并关闭此代码,返回到工作表,然后输入此公式 = removedupes1(A2) (A2 是您要从中删除重复项的数据单元)到数据之外的空白单元格,请参见屏幕截图:

4。 然后将填充手柄拖到要应用此公式的范围单元格上,所有重复的字符已立即从每个单元格中删除。

如果单元格中有些单词被某些标点符号分隔,则您也可以根据需要删除重复的单词。 请执行以下步骤:

1. 按住 ALT + F11 键打开 Microsoft Visual Basic for Applications窗口.

2。 点击 插页 > 模块,然后将以下代码粘贴到 模块窗口.

VBA代码:删除由单元标点符号分隔的重复单词

Function RemoveDupes2(txt As String, Optional delim As String = " ") As String
    Dim x
    'Updateby Extendoffice
    With CreateObject("Scripting.Dictionary")
        .CompareMode = vbTextCompare
        For Each x In Split(txt, delim)
            If Trim(x) <> "" And Not .exists(Trim(x)) Then .Add Trim(x), Nothing
        Next
        If .Count > 0 Then RemoveDupes2 = Join(.keys, delim)
    End With
End Function

3。 然后保存并关闭此代码,返回到工作表,然后输入此公式 = RemoveDupes2(A2,“,”) 放入数据旁边的空白单元格,请参见屏幕截图:

文档删除重复字符 1

4。 然后将公式复制到所需的单元格中,所有重复的单词已从每个单元格中删除。 看截图:

备注:在以上公式中, A2 表示您要使用的单元格,而逗号(,)代表用于分隔单元格中各个单词的标点符号,您可以根据需要将其更改为任何其他标点符号。

Not sure if this thread is still alive. I am trying to use this for something as simple as what is shown in the chart above and I keep on receiving #NAME? error. Cell A2 has XXX, YYY, XXX, AAA I can't quite understand what I am doing wrong. I have the code in my personal workbook. Would that be the issue?

Thank you for the beautiful and useful coding. Can we do the same using Power Query?

i tried applying method2 to numbers but it does not work. eg. 1104, 1104, 203, 203, 409, 409 >>>1104, 203, 409 How do you get method 2 to work with numbers?

Hello, deezy,
The second method works well for numbers, please see the below screenshot.
Please try it again, thank you!

Thanks so much for sharing knowledge, I used the "Remove Duplicate Words Separated By Punctuation With User Defined Function" and it worked great. May you knowledge grow and grow.

how about to remove duplicate character with an exception

for example from MMMPXLL, i want to remove M but keep the L

so the result will be MPXLL

Edit :

some problem solved with removedupes2, but i have to do it one by one

for example i cant remove duplicate letter y,a,l at once. I have to do it one by one.

also, for case there is data like this yyypl, it become pl, the "y" is totally removed

i have a string of text like so

1 Ser 1 Ser 1 Ser 1 Ser 1 Ser 1 Ser 1 Ser 1 Ser 1 Ser 2 Ser 2 Ser 2 Ser 2 Ser 2 Ser 2 Ser 2 Ser 2 Ser 3 Ser 3 Ser 3 Ser 3 Ser 3 Ser 3 Ser 3 Ser 3 Ser X3 X5

when applying remove dupes 2 i get

1 Ser 2 3 X3 X5


by the looks of it, all duplicates except the first instance are kept, is there any way to tweek this so all duplicate instances except the last occurance are kept ?

so my desired outcome would be

1 2 3 Ser X3 X5

thank you in advanced!
