Question

我有一个包含分配给像这样的项目的用户名的单元格

,FC757_random_name,AP372_another_one,FC782_again_different,FC082_samesamebutdifferent,

我只需要提取表达式开头的字母数字值，因此,和_之间的所有内容都是如此。

我让它适用于以下一个表达式，但我需要所有这些表达式。

= MID(A1;FIND(",";A1)+1;FIND("_";A1)-FIND(",";A1)-1)

我还修改了Text to Data，但是无法让它同时适用于多行。理想情况下，这只适用于公式，但我猜（/恐惧）我需要VBA或宏，这是我以前从未使用过的。

所有帮助将不胜感激！

Answer 1

这是基于regex的用户定义函数。

Option Explicit

Function extractMultipleExpressions(str As String, _
                  Optional delim As String = ", ")
    Dim n As Long, nums() As Variant
    Static rgx As Object, cmat As Object

    'with rgx as static, it only has to be created once; beneficial when filling a long column with this UDF
    If rgx Is Nothing Then
        Set rgx = CreateObject("VBScript.RegExp")
    End If
    extractMultipleExpressions = vbNullString

    With rgx
        .Global = True
        .MultiLine = False
        .Pattern = "[A-Z]{2}[0-9]{3}"
        If .Test(str) Then
            Set cmat = .Execute(str)
            'resize the nums array to accept the matches
            ReDim nums(cmat.Count - 1)
            'populate the nums array with the matches
            For n = LBound(nums) To UBound(nums)
                nums(n) = cmat.Item(n)
            Next n
            'convert the nums array to a delimited string
            extractMultipleExpressions = Join(nums, delim)
        End If
    End With
End Function

我相信您正在寻找类似的内容按Alt + F11，然后选择插入＆gt;模块然后粘贴以下代码：

Public Function GetUsers(UserNameProject As String)

Dim userArray() As String
Dim users As String
Dim intPos As Integer

'this will split the users into an array based on the commas
userArray = Split(UserNameProject, ",")

'loop through the array and process any non blank element and extract user
'based on the position of the first underscore
For i = LBound(userArray) To UBound(userArray)
      If Len(Trim(userArray(i))) > 0 Then
        intPos = InStr(1, userArray(i), "_")
        users = users & "," & Left(userArray(i), intPos - 1)
      End If
Next

GetUsers = users

End Function

如果你的字符串在A1中，那么将=GetUsers(A1)放在批准的单元格中即可使用。我认为这应该让你开始！

要清除额外逗号的数据，请在单元格B1中使用此公式：

=TRIM(SUBSTITUTE(SUBSTITUTE(TRIM(SUBSTITUTE(SUBSTITUTE(A1;" ";"||");";";" "));" ";";");"||";" "))

然后在单元格C1中使用此公式并上下复制以从每个部分中提取所需的部分：

=IFERROR(INDEX(TRIM(LEFT(SUBSTITUTE(TRIM(MID(SUBSTITUTE($B1;";";REPT(" ";LEN($B1)));LEN($B1)*(ROW($A$1:INDEX($A:$A;LEN($B1)-LEN(SUBSTITUTE($B1;";";""))+1))-1)+1;LEN($B1)));"_";REPT(" ";LEN($B1)));LEN($B1)));COLUMN(A1));"")

提取多个表达式
