Excel VBA 导出到文本文件。需要删除空行

Question

我有一个工作簿，我使用以下脚本将其导出到文本文件。它工作正常，但是当我打开文本文件时，末尾总是有一个空行，这导致我在生成此文本文件后运行的另一个脚本出现问题。有关如何从导出中删除空行的任何帮助。

代码:

Sub Rectangle1_Click()
     Application.DisplayAlerts = False

' Save file name and path into a variable
    template_file = ActiveWorkbook.FullName   

' Default directory would be c:\temp.  Users however will have the ability 
' to change where to save the file if need be.

      fileSaveName = Application.GetSaveAsFilename( _
        InitialFileName:="C:\users\%username%\SNSCA_Customer_" + _
        VBA.Strings.Format(Now, "mmddyyyy") + ".txt", _
        fileFilter:="Text Files (*.txt), *.txt")

    If fileSaveName = False Then
        Exit Sub
    End If

    ' Save file as .txt TAB delimited fileSaveName, FileFormat:=36,

       ActiveWorkbook.SaveAs Filename:= _
        fileSaveName, FileFormat:=xlTextWindows, _
        CreateBackup:=False

       file_name_saved = ActiveWorkbook.FullName
    MsgBox "Your SNSCA configuration upload file has been " _
       & "successfully created at: " & vbCr & vbCr & file_name_saved

End Sub

编辑...

这是一个不起作用的替代方案:

Sub Rectangle1_Click()
    Dim fPath As String
    Dim exportTxt As String
    fPath = CreateObject("WScript.Shell").SpecialFolders("Desktop") & "\Sample_" & Format(Now(), "HHNNSS") & ".txt"

    exportTxt = ActiveWorkbook.

    Open fPath For Append As #1    'write the new file
    Print #1, exportTxt;
    Close #1
End Sub

虽然我已经引用了 Jean-François Corbett 的评论，但您可以使用下面的 VBA 删除 txt 文件的最后一行(正如您所说，以这种方式保存时会写入一个空行)。

这个VBA基于常用的vbscript常规。它

• 读取新创建的文本文件，例如 (*SNSCA_Customer_01092012.txt*)
• 逐行分割

• 然后将除最后一行之外的所有行重写到新的 txt 文件(*SNSCA_Customer_01092012clean.txt*)

  Sub Rectangle1_Click()
  Dim strTemplateFile As String
  Dim strFname As String
  Dim strFnameClean As String
  Dim FileSaveName
  
  Application.DisplayAlerts = False
  ' Save file name and path into a variable
  strTemplateFile = ActiveWorkbook.FullName
  
  ' Default directory would be c:\temp.  Users however will have the ability
  ' to change where to save the file if need be.
  
  FileSaveName = Application.GetSaveAsFilename( _
                 InitialFileName:="C:\users\%username%\SNSCA_Customer_" + _
                                  VBA.Strings.Format(Now, "mmddyyyy") + ".txt", _
                 fileFilter:="Text Files (*.txt), *.txt")
  
  If FileSaveName = False Then
      Exit Sub
  End If
  
  ' Save file as .txt TAB delimited fileSaveName, FileFormat:=36,
  ActiveWorkbook.SaveAs Filename:= _
                        FileSaveName, FileFormat:=xlTextWindows, _
                        CreateBackup:=False
  
  strFname = ActiveWorkbook.FullName
  strFnameClean = Replace(ActiveWorkbook.FullName, ".txt", "clean.txt")
  MsgBox "Your SNSCA configuration upload file has been " _
       & "successfully created at: " & vbCr & vbCr & strFname
  Call Test(strFname, strFnameClean)
  End Sub
  
  
  Sub Test(ByVal strFname, ByVal strFnameClean)
  Const ForReading = 1
  Const ForWriting = 2
  
  Dim objFSO As Object
  Dim objTF As Object
  Dim strAll As String
  Dim varTxt
  Dim lngRow As Long
  
  Set objFSO = CreateObject("Scripting.FileSystemObject")
  Set objTF = objFSO.OpenTextFile(strFname, ForReading)
  strAll = objTF.readall
  objTF.Close
  Set objTF = objFSO.createTextFile(strFnameClean, ForWriting)
  varTxt = Split(strAll, vbCrLf)
  For lngRow = LBound(varTxt) To UBound(varTxt) - 1
      objTF.writeline varTxt(lngRow)
  Next
  objTF.Close
  End Sub
