是否可以计算单元格内唯一字符的数量？使用

Question

软件：Excel中的Mac 2011

我有一个包含字母数字串一列单元格，我期待计数的出现在每个小区唯一字符数。我想拥有它的功能，如下图所示：

因为我的工作数据，我不需要空间中包含或字符计数排除或任何区别是由大写或小写字符组成。

感谢您的帮助。

Answer 1

试试这个：

=SUM(IF((LEN(G13)-LEN(SUBSTITUTE(UPPER(G13),{"A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z","1","2","3","4","5","6","7","8","9","0"},""))),1,0)) 

如前所述这是相当长的。这将计算英文字母数字字符的上限和下限，但正如helena4指出的那样，您需要将其他符号添加到公式中的数组中，否则它们将不会被计数。

显然，将G13引用更改为具有所需文本的单元格以进行计数。

如果你想有一个UDF使用此：

Function Uniquecount(Rng As Range) As Integer 
Dim cUnique As Collection 
Dim i As Integer 
Set cUnique = New Collection 

On Error Resume Next 
For i = 1 To Len(Rng) 
    cUnique.Add CStr(Mid(Rng, i, 1)), CStr(Mid(Rng, i, 1)) 
Next i 
On Error GoTo 0 

Uniquecount = cUnique.Count 
End Function 

把它连接到工作簿中的模块中。然后像任何其他公式一样称呼它：=Uniquecount(G13)

这将包括空格在内的所有数据。
