VBA 用唯一的拆分条目填充列的函数

Question

我需要帮助来创建一个非常具体的 VBA 函数。我需要一个既能拆分单元格值又能用唯一值填充另一列的函数。

我目前正在使用 =IFERROR(INDEX(List,MATCH(0,INDEX(COUNTIF($A:A2,List),0,0),0)),"") 以便从一列到另一列获取唯一值。不幸的是，其中一些值将与“,”连接，但仍需要是唯一的。

不幸的是，我对 VBA 的了解远非广泛。有人有什么建议吗？

假设我们有这样的数据：

在第 A 列中。运行这个宏将提取唯一值然后放入列 B:

Sub dural()
    Dim c As Collection, K As Long
    Set c = New Collection
    K = 1
    On Error Resume Next
    For Each r In Range("A1:A" & Cells(Rows.Count, "A").End(xlUp).Row)
        ary = Split(r.Text, ",")
        For Each a In ary
            c.Add a, CStr(a)
            If Err.Number = 0 Then
                Cells(K, "B").Value = a
            K = K + 1
            Else
                Err.Number = 0
            End If
        Next a
    Next r
    On Error GoTo 0
End Sub

这里是UDF形式的相同逻辑：

Public Function UniKues(rIn As Range)
    Dim c As Collection, K As Long
    Set c = New Collection
    K = 1
    On Error Resume Next
    For Each r In rIn
        ary = Split(r.Text, ",")
        For Each a In ary
            c.Add a, CStr(a)
        Next a
    Next r

    ReDim bry(1 To c.Count, 1 To 1)
    For i = 1 To c.Count
        bry(i, 1) = c.Item(i)
    Next i
    UniKues = bry
    On Error GoTo 0

End Function

只需 hi-light 列 B 的一部分，然后在 Array[=52] 中输入 UDF =]形式

这是 UDF 和 chris neilsen 的 建议：

Public Function UniKues(rIn As Range) Dim c As Collection, K As Long, MM As Long Dim CC As Long Set c = New Collection K = 1 On Error Resume Next For Each r In rIn ary = Split(r.Text, ",") For Each a In ary c.Add a, CStr(a) Next a Next r MM = Application.Caller.Rows.Count CC = c.Count dimn = Application.WorksheetFunction.Max(MM, CC) ReDim bry(1 To dimn, 1 To 1) For i = 1 To CC bry(i, 1) = c.Item(i) Next i If MM > CC Then For i = CC + 1 To MM bry(i, 1) = "" Next i End If UniKues = bry On Error GoTo 0 End Function
