如何将包含多个值（逗号分隔）的单元格拆分为单独的行？

Question

我正在处理一个数据样本，我想根据逗号分隔符将其分成几行。拆分前我在 Excel 中的数据表如下所示：

我想开发 VBA 代码来拆分 C 列（“公司联系点”）中的值，并为每个“公司联系点”创建单独的行。

到目前为止，我已经设法将 C 列中的值拆分为单独的行。但是，我还没有设法拆分 D 列（关系长度）和 E（关系强度）中的值，以便用逗号分隔的每个值对应于 C 列中的相应联系人。

您将在下面找到我用来拆分单元格的代码示例。这段代码的限制是它没有拆分我表中的其他列，只拆分了一个。

如何使此代码能够拆分其他列中的值？

Sub Splt()
    Dim LR As Long, i As Long
    Dim X As Variant
    Application.ScreenUpdating = False
    LR = Range("A" & Rows.Count).End(xlUp).Row
    Columns("A").Insert
    For i = LR To 1 Step -1
        With Range("B" & i)
            If InStr(.Value, ",") = 0 Then
                .Offset(, -1).Value = .Value
            Else
                X = Split(.Value, ",")
                .Offset(1).Resize(UBound(X)).EntireRow.Insert
                .Offset(, -1).Resize(UBound(X) - LBound(X) + 1).Value = Application.Transpose(X)
            End If
        End With
    Next i
    Columns("B").Delete
    LR = Range("A" & Rows.Count).End(xlUp).Row
    With Range("B1:C" & LR)
        On Error Resume Next
            .SpecialCells(xlCellTypeBlanks).FormulaR1C1 = "=R[-1]C"
         On Error GoTo 0
         .Value = .Value
    End With

    Application.ScreenUpdating = True
End Sub

Answer 1

您不仅应该迭代行，还应该迭代列，并检查每个单元格中是否有这样的逗号。当一行中至少有一个单元格有逗号时，应将其拆分。

然后您可以插入该行，并将逗号之前的部分复制到新创建的行中，同时从原始行中删除该部分，然后将其向上移动一个索引。

您还应该注意在插入行时增加要遍历的行数，否则您将完成一项不完整的工作。

这是您可以使用的代码：

Sub Splt()
    Dim LR As Long, LC As Long, r As Long, c As Long, pos As Long
    Dim v As Variant

    Application.ScreenUpdating = False
    LR = Cells(Rows.Count, 1).End(xlUp).Row
    LC = Cells(1, Columns.Count).End(xlToLeft).Column
    r = 2
    Do While r <= LR
        For c = 1 To LC
            v = Cells(r, c).Value
            If InStr(v, ",") Then Exit For ' we need to split
        Next
        If c <= LC Then ' We need to split
            Rows(r).EntireRow.Insert
            LR = LR + 1
            For c = 1 To LC
                v = Cells(r + 1, c).Value
                pos = InStr(v, ",")
                If pos Then
                    Cells(r, c).Value = Left(v, pos - 1)
                    Cells(r + 1, c).Value = Trim(Mid(v, pos + 1))
                Else
                    Cells(r, c).Value = v
                End If
            Next
        End If
        r = r + 1
    Loop
    Application.ScreenUpdating = True
End Sub

我会采用一种方法，使用用户定义的对象（类）和字典来收集和重组数据。使用易于理解的名称，以便日后维护和调试。

此外，通过使用 VBA 数组，宏的执行速度应该比对工作表的多次读取和写入要快得多

然后将数据重新编译成所需的格式。

我定义的两个类

• 站点（我假设每个站点只有一个站点联系人，尽管如果需要，很容易更改），并提供以下信息：

  • 网站名称
  • 网站主要联系人
  • 和公司联系信息字典

• 公司联系人，其中包含以下信息

  • 姓名
  • 关系长度
  • 关系强度

我会检查以确保最后三列中的条目数量相同。

如您所见，如果需要，向任一类添加额外信息将相当简单。

输入两个类模块和一个常规模块 重命名 Class Modules 如 cmets 所示

请务必设置对 Microsoft Scripting Runtime 的引用，以便能够使用 Dictionary 对象。

此外，您可能需要为源/结果工作表/范围重新定义 wsSrc、wsRes 和 rRes。为方便起见，我将它们放在同一个工作表上，但没有必要。

类模块 1

Option Explicit
'Rename this to: cSite
'Assuming only a single Site Key Contact per site

Private pSite As String
Private pSiteKeyContact As String
Private pCompanyContactInfo As Dictionary
Private pCC As cCompanyContact

Public Property Get Site() As String
    Site = pSite
End Property
Public Property Let Site(Value As String)
    pSite = Value
End Property

Public Property Get SiteKeyContact() As String
    SiteKeyContact = pSiteKeyContact
End Property
Public Property Let SiteKeyContact(Value As String)
    pSiteKeyContact = Value
End Property

Public Property Get CompanyContactInfo() As Dictionary
    Set CompanyContactInfo = pCompanyContactInfo
End Property

Public Function AddCompanyContactInfo(ByVal CompanyContact As String, _
    ByVal RelationshipLength As String, ByVal RelationshipStrength As String)
    Set pCC = New cCompanyContact
    With pCC
        .CompanyContact = CompanyContact
        .LengthOfRelationship = RelationshipLength
        .StrengthOfRelationship = RelationshipStrength
        pCompanyContactInfo.Add Key:=.CompanyContact, Item:=pCC
    End With
End Function

Private Sub Class_Initialize()
    Set pCompanyContactInfo = New Dictionary
End Sub

类模块 2

Option Explicit

    CompanyContact = pCompanyContact
End Property
Public Property Let CompanyContact(Value As String)
    pCompanyContact = Value
End Property

Public Property Get LengthOfRelationship() As String
    LengthOfRelationship = pLengthOfRelationship
End Property
Public Property Let LengthOfRelationship(Value As String)
    pLengthOfRelationship = Value
End Property

Public Property Get StrengthOfRelationship() As String
    StrengthOfRelationship = pStrengthOfRelationship

Public Property Let StrengthOfRelationship(Value As String)
    pStrengthOfRelationship = Value
