Excel：将工作表导出为 CSV 文件的宏，无需离开我当前的 Excel 工作表

Question

这里有很多问题要创建一个宏来将工作表保存为 CSV 文件。所有答案都使用 SaveAs，例如来自 SuperUser 的this one。他们基本上说要像这样创建一个 VBA 函数：

Sub SaveAsCSV()
    ActiveWorkbook.SaveAs FileFormat:=clCSV, CreateBackup:=False
End Sub

这是一个很好的答案，但我想做一个导出而不是另存为。当 SaveAs 被执行时，它给我带来了两个烦恼：

• 我当前的工作文件变成了 CSV 文件。我想继续使用我原来的 .xlsm 文件，但要将当前工作表的内容导出到同名的 CSV 文件中。
• 出现一个对话框，要求我确认是否要重写 CSV 文件。

是否可以仅将当前工作表导出为文件，但继续在我的原始文件中工作？

Answer 1

@NathanClement 有点快。然而，这里是完整的代码（稍微详细一点）：

Option Explicit

Public Sub ExportWorksheetAndSaveAsCSV()

Dim wbkExport As Workbook
Dim shtToExport As Worksheet

Set shtToExport = ThisWorkbook.Worksheets("Sheet1")     'Sheet to export as CSV
Set wbkExport = Application.Workbooks.Add
shtToExport.Copy Before:=wbkExport.Worksheets(wbkExport.Worksheets.Count)
Application.DisplayAlerts = False                       'Possibly overwrite without asking
wbkExport.SaveAs Filename:="C:\tmp\test.csv", FileFormat:=xlCSV
Application.DisplayAlerts = True
wbkExport.Close SaveChanges:=False

End Sub

几乎是我想要的@Ralph，但这是最佳答案，因为它解决了一些问题：

1. 它导出当前工作表，而不仅仅是名为“Sheet1”的硬编码工作表；
2. 它导出到一个名为当前工作表的文件
3. 它尊重语言环境分隔字符。
4. 您继续编辑您的 xlsx 文件。

为了解决这些问题，并满足我的所有要求，我改编了code from here。我已经对其进行了一些清理以使其更具可读性。

Option Explicit
Sub ExportAsCSV()
 
    Dim MyFileName As String
    Dim CurrentWB As Workbook, TempWB As Workbook
     
    Set CurrentWB = ActiveWorkbook
    ActiveWorkbook.ActiveSheet.UsedRange.Copy
 
    Set TempWB = Application.Workbooks.Add(1)
    With TempWB.Sheets(1).Range("A1")
      .PasteSpecial xlPasteValues
      .PasteSpecial xlPasteFormats
    End With        

    Dim Change below to "- 4"  to become compatible with .xls files
    MyFileName = CurrentWB.Path & "\" & Left(CurrentWB.Name, Len(CurrentWB.Name) - 5) & ".csv"
     
    Application.DisplayAlerts = False
    TempWB.SaveAs Filename:=MyFileName, FileFormat:=xlCSV, CreateBackup:=False, Local:=True
    TempWB.Close SaveChanges:=False
    Application.DisplayAlerts = True
End Sub

上面的代码还有一些小地方需要注意：

1. .Close 和 DisplayAlerts=True 应该在 finally 子句中，但我不知道如何在 VBA 中做到这一点
2. 仅当当前文件名有 4 个字母时才有效，例如 .xlsm。不适用于 .xls excel 旧文件。对于 3 个字符的文件扩展名，在上面的代码中设置 MyFileName 时，您必须将 - 5 更改为 - 4。
3. 作为附带效果，您的剪贴板将替换为当前工作表内容。

编辑：将Local:=True 与我的语言环境 CSV 分隔符一起保存。

根据我对@neves 帖子的评论，我通过添加 xlPasteFormats 和值部分稍微改进了这一点，因此日期作为日期进行 - 我主要将银行对帐单保存为 CSV，因此需要日期。

Sub ExportAsCSV()

    Dim MyFileName As String
    Dim CurrentWB As Workbook, TempWB As Workbook

    Set CurrentWB = ActiveWorkbook
    ActiveWorkbook.ActiveSheet.UsedRange.Copy

    Set TempWB = Application.Workbooks.Add(1)
    With TempWB.Sheets(1).Range("A1")
        .PasteSpecial xlPasteValues
        .PasteSpecial xlPasteFormats
    End With

    'Dim Change below to "- 4"  to become compatible with .xls files
    MyFileName = CurrentWB.Path & "\" & Left(CurrentWB.Name, Len(CurrentWB.Name) - 5) & ".csv"

    Application.DisplayAlerts = False
    TempWB.SaveAs Filename:=MyFileName, FileFormat:=xlCSV, CreateBackup:=False, Local:=True
    TempWB.Close SaveChanges:=False
    Application.DisplayAlerts = True
End Sub

这是对上面这个答案的轻微改进，在同一个例程中处理 .xlsx 和 .xls 文件，以防它帮助某人！

我还添加了一行以选择使用活动工作表名称而不是工作簿进行保存，这对我来说经常是最实用的：

Sub ExportAsCSV()

    Dim MyFileName As String
    Dim CurrentWB As Workbook, TempWB As Workbook

    Set CurrentWB = ActiveWorkbook
    ActiveWorkbook.ActiveSheet.UsedRange.Copy

    Set TempWB = Application.Workbooks.Add(1)
    With TempWB.Sheets(1).Range("A1")
        .PasteSpecial xlPasteValues
        .PasteSpecial xlPasteFormats
    End With

    MyFileName = CurrentWB.Path & "\" & Left(CurrentWB.Name, InStrRev(CurrentWB.Name, ".") - 1) & ".csv"
    'Optionally, comment previous line and uncomment next one to save as the current sheet name
    'MyFileName = CurrentWB.Path & "\" & CurrentWB.ActiveSheet.Name & ".csv"


    Application.DisplayAlerts = False
    TempWB.SaveAs Filename:=MyFileName, FileFormat:=xlCSV, CreateBackup:=False, Local:=True
    TempWB.Close SaveChanges:=False
    Application.DisplayAlerts = True
End Sub

对于那些需要更多自定义输出（分隔符或十进制符号）或拥有大型数据集（超过 65k 行）的情况，我写了以下内容：

Option Explicit

Sub rng2csv(rng As Range, fileName As String, Optional sep As String = ";", Optional decimalSign As String)
'export range data to a CSV file, allowing to chose the separator and decimal symbol
'can export using rng number formatting!
'by Patrick Honorez --- www.idevlop.com
    Dim f As Integer, i As Long, c As Long, r
    Dim ar, rowAr, sOut As String
    Dim replaceDecimal As Boolean, oldDec As String

    Dim a As Application:   Set a = Application

    ar = rng
    f = FreeFile()
    Open fileName For Output As #f

    oldDec = Format(0, ".")     'current client's decimal symbol
    replaceDecimal = (decimalSign <> "") And (decimalSign <> oldDec)

    For Each r In rng.Rows
        rowAr = a.Transpose(a.Transpose(r.Value))
        If replaceDecimal Then
            For c = 1 To UBound(rowAr)
                'use isnumber() to avoid cells with numbers formatted as strings
                If a.IsNumber(rowAr(c)) Then
                    'uncomment the next 3 lines to export numbers using source number formatting
'                    If r.cells(1, c).NumberFormat <> "General" Then
'                        rowAr(c) = Format$(rowAr(c), r.cells(1, c).NumberFormat)
'                    End If
                    rowAr(c) = Replace(rowAr(c), oldDec, decimalSign, 1, 1)
                End If
            Next c
        End If
        sOut = Join(rowAr, sep)
        Print #f, sOut
    Next r
    Close #f

End Sub

Sub export()
    Debug.Print Now, "Start export"
    rng2csv shOutput.Range("a1").CurrentRegion, RemoveExt(ThisWorkbook.FullName) & ".csv", ";", "."
    Debug.Print Now, "Export done"
End Sub

1. 您可以使用不带参数的 Worksheet.Copy 将工作表复制到新工作簿。 Worksheet.Move 会将工作表复制到新工作簿中，并将其从原始工作簿中删除（您可能会说“导出”它）。
2. 获取对新创建工作簿的引用并保存为 CSV。
3. 将 DisplayAlerts 设置为 false 以禁止显示警告消息。 （完成后别忘了重新打开它）。
4. 您希望在保存工作簿以及关闭工作簿时关闭 DisplayAlerts。

    wsToExport.Move

    With Workbooks
        Set wbCsv = .Item(.Count)
    End With

    Application.DisplayAlerts = False
    wbCsv.SaveAs xlCSV
    wbCsv.Close False
    Application.DisplayAlerts = True

Answer 7

正如我评论的那样，该网站上有几个地方可以将工作表的内容写入 CSV。 This one 和 this one 仅指出两个。

下面是我的版本

• 它在单元格内显式查找“，”
• 它也使用UsedRange - 因为你想获取工作表中的所有内容
• 使用数组进行循环，因为这比在工作表单元格中循环要快
• 我没有使用 FSO 例程，但这是一个选项

代码...

Sub makeCSV(theSheet As Worksheet)
Dim iFile As Long, myPath As String
Dim myArr() As Variant, outStr As String
Dim iLoop As Long, jLoop As Long

myPath = Application.ActiveWorkbook.Path
iFile = FreeFile
Open myPath & "\myCSV.csv" For Output Lock Write As #iFile

myArr = theSheet.UsedRange
For iLoop = LBound(myArr, 1) To UBound(myArr, 1)
    outStr = ""
    For jLoop = LBound(myArr, 2) To UBound(myArr, 2) - 1
        If InStr(1, myArr(iLoop, jLoop), ",") Then
            outStr = outStr & """" & myArr(iLoop, jLoop) & """" & ","
        Else
            outStr = outStr & myArr(iLoop, jLoop) & ","
        End If
    Next jLoop
    If InStr(1, myArr(iLoop, jLoop), ",") Then
        outStr = outStr & """" & myArr(iLoop, UBound(myArr, 2)) & """"
    Else
        outStr = outStr & myArr(iLoop, UBound(myArr, 2))
    End If
    Print #iFile, outStr
Next iLoop

Close iFile
Erase myArr

End Sub
