如何从VBA创建单独的CSV文件?

标签: excel vba excel-vba csv

我需要输出一些结果作为.csv文件,稍后由另一个进程解析。为了产生这些结果,我有一个庞大的工作簿,其中包含我需要的所有宏和函数。

  1. 是否可以从.csv“创建”单独的VBA文件?
  2. 是否可以使用VBA功能写入其中而不是仅仅使用“原始文本”方法进行编写?
  3. 谢谢:)

这是你想要的吗?

Option Explicit
Sub WriteFile()

  Dim ColNum As Integer
  Dim Line As String
  Dim LineValues() As Variant
  Dim OutputFileNum As Integer
  Dim PathName As String
  Dim RowNum As Integer
  Dim SheetValues() As Variant

  PathName = Application.ActiveWorkbook.Path
  OutputFileNum = FreeFile

  Open PathName & "\Test.csv" For Output Lock Write As #OutputFileNum

  Print #OutputFileNum, "Field1" & "," & "Field2"

  SheetValues = Sheets("Sheet1").Range("A1:H9").Value
  ReDim LineValues(1 To 8)

  For RowNum = 1 To 9
    For ColNum = 1 To 8
      LineValues(ColNum) = SheetValues(RowNum, ColNum)
    Next
    Line = Join(LineValues, ",")
    Print #OutputFileNum, Line
  Next

  Close OutputFileNum

End Sub

不要忘记您需要在包含逗号的任何字段周围加上引号。

Tony的答案通常有效,但不处理您的文字包含逗号或引号的情况。您可能更喜欢使用Workbook.SaveAs方法。

如果要将Sheet1的内容另存为单独的csv文件,请执行以下示例。

Sub create_csv()
    Dim FileName As String
    Dim PathName As String
    Dim ws As Worksheet

    Set ws = ActiveWorkbook.Sheets("Sheet1")
    FileName = "filename.csv"
    PathName = Application.ActiveWorkbook.Path
    ws.Copy
    ActiveWorkbook.SaveAs FileName:=PathName & "\" & FileName, _
        FileFormat:=xlCSV, CreateBackup:=False
End Sub

想象一下,您的Sheet1包含:

  

lorem ipsum

     

lore,m ips"嗯"

输出csv文件将是:

  

LOREM,存有

     

"传说,米"" IPS""嗯"""

您可以编写一个宏,以便从VBA以CSV格式保存当前工作簿(打开的Excel文件):

ActiveWorkbook.SaveAs Filename:="C:\Book1.csv", _
    FileFormat:=xlCSVMSDOS, CreateBackup:=False

对于那些手动编写 CSV 的人,您需要处理逗号、双引号和换行符。

例如

Sub WriteToCsv(Items() as String)

    OutFile = FreeFile          
    Open "Outfile.csv" For Output As #OutFile
    
    Print #OutFile, "Header"
    
    For Each Item In Items       
        If InStr(1, Item, Chr(34)) > 0 Then Item = Chr(34) & Replace(Item, Chr(34), Chr(34) & Chr(34)) & Chr(34)
        If InStr(1, Item, ",") > 0 And Left(Item, 1) <> Chr(34) Then Item = Chr(34) & Item & Chr(34)
        If InStr(1, Item, vbLf) > 0 And Left(Item, 1) <> Chr(34) Then Item = Chr(34) & Item & Chr(34)
        Print #OutFile, Item
    Next
    
    Close OutFile

End Sub
