Excel /如何比较单元格中的字符

我想比较单元格中的字符并返回剩余的字符。 例如，

A1 =（111,222,444,555）

B1 =（111,222,333,444,555,666）

那么，我想看看C1的遗体，

C1 =（333,666）

有什么办法，我可以用Excelfunction呢？ 我必须用VBA代码做这个吗？ 提前致谢！

在Tim的评论的基础上，一个可能的UDF可能看起来像这样。

Public Function GetDiff(rngFirst As Range, rngSecond As Range) As String Dim arrFirst Dim arrSecond Dim lRctr1 As Long Dim lRctr2 As Long Dim bMatch As Boolean Dim strResult As String arrFirst = Split(IIf(Len(rngFirst) >= Len(rngSecond), rngFirst, rngSecond), ",") arrSecond = Split(IIf(Len(rngFirst) <= Len(rngSecond), rngFirst, rngSecond), ",") For lRctr1 = LBound(arrFirst) To UBound(arrFirst) bMatch = False For lRctr2 = LBound(arrSecond) To UBound(arrSecond) If (arrFirst(lRctr1) = arrSecond(lRctr2)) Then lRctr2 = UBound(arrSecond) + 1 bMatch = True End If Next If Not bMatch Then strResult = strResult & arrFirst(lRctr1) & "," End If Next If Len(strResult) > 0 Then strResult = Mid(strResult, 1, Len(strResult) - 1) End If GetDiff = strResult End Function

只要在模块中添加上面的代码，然后你可以像这样使用它，比如说单元格C1 =GetDiff(A1,B1)
