我有工作簿，我遍历并将每个工作表保存为csv。问题是当循环完成Excel时会提示我保存。如果我单击“保存”，那么最后一个工作表将被Excel工作簿打开的哪个工作表覆盖。
如果单击“不保存”，一切都保持保存正确的数据，但我不能依赖用户每次都单击“不保存”，所以我需要找到我的代码在保存时过度写入数据的位置。
如何防止我的csv工作表被覆盖？
Sub LipperFormat()
'Create Workbook
Dim wb As Workbook
'Get FilePath
Dim wbActive As Workbook
Set wbActive = ActiveWorkbook
Dim wsActive As Worksheet
Set wsActive = wbActive.Worksheets(1)
'Get File Path
Dim filePath As String
Dim rngActive As Range
Set rngActive = wsActive.Cells(1, 2)
filePath = rngActive.Value
'Open File
Set wb = Workbooks.Open(filePath)
'Create Copy of file and CSV
Dim copyFilePath As String
Dim fileExtension As String: fileExtension = "_OG.xlsx"
copyFilePath = Left(filePath, Len(filePath) - 5) + fileExtension
wb.SaveCopyAs copyFilePath
'Loop through worksheets
Dim WS_Count As Integer
Dim i As Integer
WS_Count = wb.Worksheets.Count
For i = 1 To WS_Count
Dim col As Integer
Dim ws As Worksheet
Set ws = wb.Sheets(i)
'Save As CSV
Dim sheetName As String: sheetName = ws.Name
Dim csvFilePath As String
Dim csvSheet As Worksheet
cvsFilePath = Left(filePath, Len(filePath) - 5) + "__" + sheetName
'ws.Name = sheetName
ws.SaveAs FileName:=cvsFilePath, FileFormat:=xlCSV, CreateBackup:=False
Next i
'wb.Save
wb.Close
End Sub
你的代码太大了，没有任何好处。我清理了它并纠正了你的错误，还添加了必要的部分，不要向用户要求任何东西：
Sub LipperFormat()
Dim filePath As String
Dim csvFileName As String
Dim ws As Worksheet
Dim wb As Workbook
Application.DisplayAlerts = False
'define parameters
Set wb = ThisWorkbook
Set ws = wb.Worksheets(1) 'it is better to define it with the name, not with its index
filePath = ws.Cells(1, 2).Value
'Open File
Set wb = Workbooks.Open(Filename:=filePath, ReadOnly:=True)
'loop and save as csv
For Each ws In wb.Worksheets
csvFileName = wb.Path & "\" & Left(wb.Name, Len(wb.Name) - 5) & "__" & ws.Name
ws.Copy
ActiveWorkbook.SaveAs Filename:=csvFileName, FileFormat:=xlCSV, CreateBackup:=True
ActiveWorkbook.Close
Next ws
'close WB
wb.Close
Application.DisplayAlerts = True
End Sub
