从 Excel 中包含逗号分隔值的两个单元格中提取公共值

有没有一种简单的方法可以从两个以逗号分隔的数字单元格中提取共同的数字？

我有单元格，每个单元格中有 12 个逗号分隔的数字。 （它们并不都是唯一的。有些数字可以重复两次。但不能超过两次。数字都是正数，并且只能是一位或两位数字）

我的数据是这样的：它们在A列中：

11,11,13,15,16,18,20,20,26,27,28,29
8,9,10,12,13,14,18,20,21,22,24,28
13,13,14,14,15,17,18,19,20,21,23,25
6,6,8,10,12,14,15,17,18,20,20,25
11,13,17,18,19,19,22,25,26,28,28,31
7,9,15,16,17,18,23,24,24,25,26,27
7,9,11,12,12,15,16,16,18,18,20,23
9,11,13,15,18,22,23,24,25,28,29,29
7,9,10,11,12,12,13,14,15,16,19,22
5,10,11,12,12,16,17,18,20,22,24,25
7,10,13,16,16,17,18,19,21,23,24,24
10,14,16,18,18,19,21,23,23,25,27,28

我想要的结果是这样的：

我需要一个解决方案没有分离值请分到不同的栏目中。 感谢您的帮助。

由于在某些情况下数字可能会重复两次，所以我also也对这样的解决方案持开放态度。

匹配子字符串

这是更简单的“重复”解决方案：

In Excel像这样使用它：

=comStr(A2,A3)

将代码复制到标准模块中，例如Module1

The Code

Option Explicit

Function comStr(String1 As String, _
                 String2 As String, _
                 Optional ByVal Delimiter As String = ",") _
         As String
         
    Dim Data1, Data2, Result(), i As Long, j As Long, l As Long
    Data1 = Split(String1, Delimiter)
    Data2 = Split(String2, Delimiter)
    For i = 0 To UBound(Data1)
        For j = 0 To UBound(Data2)
            If Data1(i) = Data2(j) Then GoSub writeResult: Exit For
        Next j
    Next i
                    
    comStr = Join(Result, Delimiter)

    Exit Function

writeResult:
    ReDim Preserve Result(l)
    Result(l) = Data1(i)
    l = l + 1
    Return

End Function

EDIT:

这是“完整”版本，您可以选择是否允许重复。

In Excel像这样使用它：

=comStr(A2,A3,TRUE)允许重复（如上面的版本）或=comStr(A2,A3) or =comStr(A2,A3,FALSE)不允许他们。

Function comStr(String1 As String, _
                 String2 As String, _
                 Optional allowDupes As Boolean = False, _
                 Optional ByVal Delimiter As String = ",") _
         As String
         
    Dim Data1, Data2, Result(), Curr, i As Long, j As Long, l As Long, n As Long
    Data1 = Split(String1, Delimiter)
    Data2 = Split(String2, Delimiter)
    For i = 0 To UBound(Data1)
        Curr = Data1(i)
        For j = 0 To UBound(Data2)
            If Data2(j) = Curr Then GoSub writeResult: Exit For
        Next j
    Next i
                    
    If l = 0 Then Exit Function
    comStr = Join(Result, Delimiter)

    Exit Function

writeResult:
    If Not allowDupes Then
        If l > 0 Then
            For n = 0 To l - 1
                If Result(n) = Curr Then Exit For
            Next
            If n <= l - 1 Then Return
        End If
    End If
    ReDim Preserve Result(l)
    Result(l) = Data1(i)
    l = l + 1
    Return

End Function
