我正在使用下面的代码将一列逗号分隔的列表砍掉,并将每个条目返回到新的行中。
Sub SliceNDice()

' Splits the locations cells according to commas and pushes to new rows

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, "c").End(xlUp)).Value2
ReDim Y(1 To 3, 1 To 1000)
For lngRow = 1 To UBound(x, 1)
'Split each string by ","
tempArr = Split(x(lngRow, 3), ",")
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 3, 1 To lngCnt + 1000)
Y(1, lngCnt) = x(lngRow, 1)
Y(2, lngCnt) = x(lngRow, 2)
Y(3, lngCnt) = objRegex.Replace(strArr, "$1")
Next
Next lngRow
'Dump the re-ordered range to columns E:G
[e1].Resize(lngCnt, 3).Value2 = Application.Transpose(Y)
End Sub
虽然这段代码工作得很完美,但它有一个致命的缺陷,即C列单元格中的任何双逗号都会导致空白单元格被推送到G列的新行中。
有谁知道如何编辑这段代码,使它不会在G列中创建带有空单元格的新行,而是跳过它们,并在它们的位置上输入下一行,就好像C列中根本没有多余的逗号一样?
只需在For Each strArr In tempArr循环内测试strArr的字符串长度作为第一个操作。
For Each strArr In tempArr
If CBool(Len(strArr)) Then
lngCnt = lngCnt + 1
'Add another 1000 records to resorted array every 1000 records
If lngCnt Mod 1000 = 0 Then ReDim Preserve Y(1 To 3, 1 To lngCnt + 1000)
Y(1, lngCnt) = x(lngRow, 1)
Y(2, lngCnt) = x(lngRow, 2)
Y(3, lngCnt) = objRegex.Replace(strArr, "$1")
End If
Next strArr
你可以对双逗号的出现进行循环清理输入,而不是固定输出,这里有一个工作实例。
文本在A1中。Hello,,World,This,,Is,,,,,,,A,,Test
Sub TestString()
Dim MyString As String
MyString = Range("A1").Text
Do Until Len(MyString) = Len(Replace(MyString, ",,", ","))
MyString = Replace(MyString, ",,", ",")
Loop
MsgBox MyString
End Sub
你可以在分割之前这样做
如果你想把它作为一个函数(在你的情况下会更好),可以这样做。
Function FixDoubleComma(MyString As String)
Do Until Len(MyString) = Len(Replace(MyString, ",,", ","))
MyString = Replace(MyString, ",,", ",")
Loop
FixDoubleComma = MyString
End Function
然后在你的代码中替换这个
tempArr = Split(x(lngRow, 3), ",")
用这个代替
tempArr = Split(FixDoubleComma(x(lngRow, 3)), ",")
我有个小例子可以解决到处都是空白的问题。
Sub RemoveBlanks()
Dim mystr As String
Dim arrWithBlanks() As String
Dim arrNoBlanks() As String
Dim i As Integer
mystr = ",tom,jerry, ,,spike,," 'Blanks everywhere (beginning, middle and end)
arrWithBlanks = Split(mystr, ",")
ReDim arrNoBlanks(0 To 0)
Debug.Print "Array with blanks:"
'Loop through the array with blanks
For i = LBound(arrWithBlanks) To UBound(arrWithBlanks)
'Check if there is a blank (or element with spaces only)
If Trim(arrWithBlanks(i)) = "" Then
Debug.Print i & " (blank)"
Else
Debug.Print i & " " & arrWithBlanks(i)
If arrNoBlanks(UBound(arrNoBlanks)) <> "" Then ReDim Preserve arrNoBlanks(0 To UBound(arrNoBlanks) + 1)
arrNoBlanks(UBound(arrNoBlanks)) = arrWithBlanks(i)
End If
Next i
Debug.Print "Array with NO blanks:"
For i = LBound(arrNoBlanks) To UBound(arrNoBlanks)
Debug.Print i & " " & arrNoBlanks(i)
Next i
End Sub
所有的东西都会在眼前的窗口中显示出来(按下 Ctrl + G 以显示它)
结果会是这样的。
Array with blanks:
0 (blank)
1 tom
2 jerry
3 (blank)
4 (blank)
5 spike
6 (blank)
7 (blank)
Array with NO blanks:
0 tom
1 jerry
2 spike
