Question

我遇到了VBA代码（下面链接），我发现通过定义分隔符将数据从文本文件导入单独的单元格非常有用。当前代码允许指定单个文件并从中提取数据。我希望实现的是从多个文本文件中提取数据，并将每个文件中的数据添加到excel中的新行中。我在尝试在代码中添加循环以实现此目的时遇到困难。

您能告诉我们如何实现这一目标吗？

Sub ImportTextFile()

Dim RowNdx As Long
Dim ColNdx As Integer
Dim TempVal As Variant
Dim WholeLine As String
Dim Pos As Integer
Dim NextPos As Integer
Dim SaveColNdx As Integer

FName = "C:\Users\40044600\Documents\zdump\"
MyFile = Dir(FName & "*.txt")
Sep = vbLf

SaveColNdx = ActiveCell.Column
RowNdx = ActiveCell.Row

Do While MyFile <> ""
    Open (FName & MyFile) For Input As #1

    While Not EOF(1)
        Line Input #1, WholeLine
        If Right(WholeLine, 1) <> Sep Then
            WholeLine = WholeLine & Sep
        End If
        ColNdx = SaveColNdx
        Pos = 1
        NextPos = InStr(Pos, WholeLine, Sep)
        While NextPos >= 1
            TempVal = Mid(WholeLine, Pos, NextPos - Pos)
            Cells(RowNdx, ColNdx).Value = TempVal
            Pos = NextPos + 1
            ColNdx = ColNdx + 1
            NextPos = InStr(Pos, WholeLine, Sep)
        Wend
        RowNdx = RowNdx + 1
    Wend
    Close #1
    MyFile = Dir()
    Debug.Print text
Loop

Answer 1

设置： 在test.txt文件中：

具有相同布局的其他文本文件是在同一目录中创建的。

在电子表格中 请注意单元格列标题和活动单元格位置。

单个文件代码包装在读取多个文件的代码中，然后调用单个文件代码。。在此示例中，使用了所有文本文件。（ test * .txt ），并测试其名称的开头。

Sub TxtFiles()
    Dim strFileName As String
    Dim strFolder As String
    Dim strFileSpec As String

    'TODO: Specify path spec
    strFolder = "C:\Users\007\Documents\Programming\VBA\Excel"
    'TODO: Specify file spec
    strFileSpec = strFolder & "\test*.txt"

    strFileName = Dir(strFileSpec)
    Do While Len(strFileName) > 0
        Call ImportTextFile(strFileName, "|")
        'move active cell location to next available empty cell row in column A.
        Range("A1").End(xlDown).Offset(1, 0).Select
        'Read next filename
        strFileName = Dir
    Loop
End Sub

上面的代码从 ImportTextFile 调用以下代码：

''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' ImportTextFile
' This imports a text file into Excel.
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Public Sub ImportTextFile(FName As String, Sep As String)

    Dim RowNdx As Long
    Dim ColNdx As Integer
    Dim TempVal As Variant
    Dim WholeLine As String
    Dim Pos As Integer
    Dim NextPos As Integer
    Dim SaveColNdx As Integer

    Application.ScreenUpdating = False
    On Error GoTo EndMacro:

    SaveColNdx = ActiveCell.Column
    RowNdx = ActiveCell.Row

    Open FName For Input Access Read As #1

    While Not EOF(1)
        Line Input #1, WholeLine
        If Right(WholeLine, 1) <> Sep Then
            WholeLine = WholeLine & Sep
        End If
        ColNdx = SaveColNdx
        Pos = 1
        NextPos = InStr(Pos, WholeLine, Sep)
        While NextPos >= 1
            TempVal = Mid(WholeLine, Pos, NextPos - Pos)
            Cells(RowNdx, ColNdx).Value = TempVal
            Pos = NextPos + 1
            ColNdx = ColNdx + 1
            NextPos = InStr(Pos, WholeLine, Sep)
        Wend
        RowNdx = RowNdx + 1
    Wend

EndMacro:
    On Error GoTo 0
    Application.ScreenUpdating = True
    Close #1
    ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
    ' END ImportTextFile
    ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
End Sub

最终结果如下：
