Vba 如何将包含多个值（逗号分隔）的单元格拆分为单独的行？

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

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

到目前为止，我已经成功地将C列中的值拆分为单独的行。但是，我还没有将D列（关系的长度）和E列（关系的强度）中的值进行拆分，以便用逗号分隔的每个值对应于C列中相应的触点

下面是我用来拆分单元格的代码示例。这段代码的局限性在于它没有拆分表中的其他列，只拆分了一列

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

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

然后可以插入该行，并在新创建的行中复制逗号之前的部分，同时从原始行中删除该部分，然后将原始行上移一个索引

在插入行时，还应注意增加要遍历的行数，否则将执行不完整的作业

以下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

子Splt（）
尺寸LR为长，LC为长，r为长，c为长，pos为长
Dim v作为变体
Application.ScreenUpdating=False
LR=单元格（Rows.Count，1）.End（xlUp）.Row
LC=单元格（1，Columns.Count）.End（xlToLeft）.Column
r=2
Do While r我会采用一种方法，使用用户定义的对象（类）和字典来收集和重新组织数据。使用可理解的名称，以便于将来的维护和调试

此外，通过使用VBA数组，宏的执行速度应该比多次读取和写入工作表快得多

然后将数据重新编译成所需的格式

我定义的两个类是


站点（我假设每个站点只有一个站点联系人，尽管这很容易更改，如果需要的话），包含以下信息：


站点名称
站点关键联系人
还有一本公司联系信息字典

公司联系人，其中包含以下信息：


名字
关系长度
关系强度


我会检查以确保在最后三列中有相同数量的条目

正如您所看到的，如果需要的话，向任何一个类添加额外的信息都是相当简单的

输入两个类模块和一个常规模块
重命名类模块，如注释中所示

确保设置对Microsoft脚本运行时的引用，以便能够使用Dictionary对象

此外，您可能需要为源代码/结果工作表/范围重新定义
wsSrc
、
wsRes
和
rRes
。为了方便起见，我把它们放在同一张工作表上，但没有必要这样做
