将逗号分隔的条目拆分为新行

Question

我目前在一张纸上有这些数据

Col A   Col B
1       angry birds, gaming
2       nirvana,rock,band

我想要做的是拆分第二列中逗号分隔的条目并插入新行,如下所示:

Col A   Col B
1   angry birds
1   gaming
2   nirvana
2   rock
2   band

我相信这可以通过VBA完成,但无法自己解决.

Answer 1

你最好使用变量数组而不是单元循环 - 一旦数据集有意义,它们的代码就会快得多.即使你的代码更长:)

下面的示例转储到C列和D列,以便您可以看到原始数据.更改[c1].Resize(lngCnt, 2).Value2 = Application.Transpose(Y)为[a1].Resize(lngCnt, 2).Value2 = Application.Transpose(Y)转储原始数据

[更新后使用regexp删除任何空格,,即","band"变为"band"]

Sub SliceNDice() 
Dim objRegex As Object 
Dim X 
Dim Y 
Dim lngRow As Long 
Dim lngCnt As Long 
Dim tempArr() As String 
Dim strArr 
Set objRegex = CreateObject("vbscript.regexp") 
objRegex.Pattern = "^\s+(.+?)$" 
 'Define the range to be analysed
X = Range([a1], Cells(Rows.Count, "b").End(xlUp)).Value2 
Redim Y(1 To 2, 1 To 1000) 
For lngRow = 1 To UBound(X, 1) 
     'Split each string by ","
    tempArr = Split(X(lngRow, 2), ",") 
    For Each strArr In tempArr 
        lngCnt = lngCnt + 1 
         'Add another 1000 records to resorted array every 1000 records
        If lngCnt Mod 1000 = 0 Then Redim Preserve Y(1 To 2, 1 To lngCnt + 1000) 
        Y(1, lngCnt) = X(lngRow, 1) 
        Y(2, lngCnt) = objRegex.Replace(strArr, "$1") 
    Next 
Next lngRow 
 'Dump the re-ordered range to columns C:D
[c1].Resize(lngCnt, 2).Value2 = Application.Transpose(Y) 
End Sub

在A列中获取数据并将结果放在C列中.

Sub SplitAll()
    Dim src As Range
    Dim result As Variant
    For Each src In Range("A:A").SpecialCells(xlCellTypeConstants)
        result = Split(src, ",")
        'last cell in column C
        With Cells(Rows.Count, 3).End(xlUp)
            Range(.Offset(1, 0), .Offset(1 + UBound(result, 1), 0)) = Application.WorksheetFunction.Transpose(result)
        End With
    Next src
End Sub
