计算逗号分隔列表中的重复值

Question

我在A列中的数据具有逗号分隔的值（一个/两位数字）。 我需要一种方法来计算两个连续行中的重复次数。

示例数据：

DATA              Expected Results
1,2,3,4,5                4
2,3,4,5                  2
3,4                      0
10,11,40,60,72,75        3
10,40,3,75  

请注意，每个列表没有相同数量的值。 A1有5个值，A2有4个值，A3有2个，依此类推。

我将不胜感激。谢谢！

Answer 1

这是B2的一种选择：

=IFERROR(SUMPRODUCT(--(1*TRIM(MID(SUBSTITUTE(A2,",",REPT(" ",99)),(ROW(INDEX(AAA:AAA,1):INDEX(AAA:AAA,LEN(A2)-LEN(SUBSTITUTE(A2,",",""))+1))-1)*99+1,99))=(TRANSPOSE(1*TRIM(MID(SUBSTITUTE(A3,",",REPT(" ",99)),(ROW(INDEX(AAA:AAA,1):INDEX(AAA:AAA,LEN(A3)-LEN(SUBSTITUTE(A3,",",""))+1))-1)*99+1,99)))))),"")

通过 Ctrl Shift Enter

输入

向下拖动...

由于我的Excel版本，图片显示点，因为我无法使用逗号。

从here借来了一些知识

Answer 2

作为VBA替代

Public Function commonCount(aRng As Range, bRng As Range) As Integer
Dim bArr() As String, aArr() As String, a As Integer, b As Integer

aArr = Split(aRng.Value, ",")
bArr = Split(bRng.Value, ",")

For a = LBound(aArr) To UBound(aArr)
    For b = LBound(bArr) To UBound(bArr)
        If aArr(a) = bArr(b) Then
            commonCount = commonCount + 1
            GoTo nexta
        End If
    Next b
nexta:
Next a

End Function

在B2 commonCount(A2,A3)
