Excel宏-逗号分隔单元格来保存/聚合列

I had a similar question answered Here

我有一个类似的问题

There is a slight twist to the scenario and hoping the macro can be changed slightly. Any help is appreciated.

这一场景有一个小小的转折，希望宏能稍微改变一下。任何帮助都是感激。

Based on this Data:

基于这个数据:

    <- A (Category) ->   <- B (Items) -> 
1   Cat1                 a,b, c
2   Cat2                 d
3   Cat3                 e
4   Cat4                 f, g

I need this:

我需要这个:

    <- A (Category) ->   <- B (Items) -> 
1   Cat1                 a
2   Cat1                 b
3   Cat1                 c
4   Cat2                 d
5   Cat3                 e
6   Cat4                 f
7   Cat4                 g

This is the existing Macro:

这是现有的宏:

Option Explicit
Sub Macro1()
    Dim fromCol As String
    Dim toCol As String
    Dim fromRow As String
    Dim toRow As String
    Dim inVal As String
    Dim outVal As String
    Dim commaPos As Integer

    ' Copy from column A to column B.'
    fromCol = "A"
    toCol = "B"
    fromRow = "1"
    toRow = "1"

    ' Go until no more entries in column A.'
    inVal = Range(fromCol + fromRow).Value
    While inVal <> ""

        ' Go until all sub-entries used up.'
        While inVal <> ""
            Range(fromCol + fromRow).Select

            ' Extract each subentry.'
            commaPos = InStr(1, inVal, ",")
            While commaPos <> 0

                ' and write to output column.'
                outVal = Left(inVal, commaPos - 1)
                Range(toCol + toRow).Select
                Range(toCol + toRow).Value = outVal
                toRow = Mid(Str(Val(toRow) + 1), 2)

                ' Remove that sub-entry.'
                inVal = Mid(inVal, commaPos + 1)
                While Left(inVal, 1) = " "
                    inVal = Mid(inVal, 2)
                Wend
                commaPos = InStr(1, inVal, ",")
            Wend

            ' Get last sub-entry (or full entry if no commas).'
            Range(toCol + toRow).Select
            Range(toCol + toRow).Value = inVal
            toRow = Mid(Str(Val(toRow) + 1), 2)
            inVal = ""
        Wend

        ' Advance to next source row.'
        fromRow = Mid(Str(Val(fromRow) + 1), 2)
        Range(fromCol + fromRow).Select
        inVal = Range(fromCol + fromRow).Value
    Wend
End Sub

I think this will work for you:

我想这对你会有用:

Sub ExpandData()
    Const FirstRow = 2
    Dim LastRow As Long
    LastRow = Range("A" & CStr(Rows.Count)).End(xlUp).Row

    ' Get the values from the worksheet
    Dim SourceRange As Range
    Set SourceRange = Range("A" & CStr(FirstRow) & ":B" & CStr(LastRow))

    ' Get sourcerange values into an array
    Dim Vals() As Variant
    Vals = SourceRange.Value

    ' Loop through the rows in the array and split each comma-delimited list of items and put each on its own row
    Dim ArrIdx As Long
    Dim RowCount As Long
    For ArrIdx = LBound(Vals, 1) To UBound(Vals, 1)

        Dim CurrCat As String
        CurrCat = Vals(ArrIdx, 1)

        Dim CurrList As String
        CurrList = Replace(Vals(ArrIdx, 2), " ", "")

        Dim ListItems() As String
        ListItems = Split(CurrList, ",")

        Dim ListIdx As Integer
        For ListIdx = LBound(ListItems) To UBound(ListItems)

            Range("A" & CStr(FirstRow + RowCount)).Value = CurrCat
            Range("B" & CStr(FirstRow + RowCount)).Value = ListItems(ListIdx)
            RowCount = RowCount + 1

        Next ListIdx

    Next ArrIdx

End Sub
