Question

在互联网上搜索了很多内容之后，我尝试将一个有效的Excel VBA代码组合在一起，将一个文件夹中的所有.csv文件读入一个excel文件（每个文件都在一个单独的工作表中）。但我唯一需要的是将所有csv文件合并到一个工作表中....

工作代码是：

将工作文件分成单独的工作表

Sub Example12()
Dim MyPath As String
Dim FilesInPath As String
Dim MyFiles() As String
Dim SourceRcount As Long
Dim Fnum As Long
Dim mybook As Workbook
Dim basebook As Workbook

'Fill in the path\folder where the files are
'on your machine
MyPath = "c:\Data"

'Add a slash at the end if the user forget it
If Right(MyPath, 1) <> "\" Then
MyPath = MyPath & "\"
End If

'If there are no Excel files in the folder exit the sub
FilesInPath = Dir(MyPath & "*.csv")
If FilesInPath = "" Then
MsgBox "No files found"
Exit Sub
End If

On Error GoTo CleanUp

Application.ScreenUpdating = False
Set basebook = ThisWorkbook

'Fill the array(myFiles)with the list of Excel files in the folder
Fnum = 0
Do While FilesInPath <> ""
Fnum = Fnum + 1
ReDim Preserve MyFiles(1 To Fnum)
MyFiles(Fnum) = FilesInPath
FilesInPath = Dir()
Loop

'Loop through all files in the array(myFiles)
If Fnum > 0 Then
For Fnum = LBound(MyFiles) To UBound(MyFiles)
Set mybook = Workbooks.Open(MyPath & MyFiles(Fnum))
mybook.Worksheets(1).Copy after:= _
basebook.Sheets(basebook.Sheets.Count)

On Error Resume Next
ActiveSheet.Name = mybook.Name
On Error GoTo 0

' You can use this if you want to copy only the values
' With ActiveSheet.UsedRange
' .Value = .Value
' End With

mybook.Close savechanges:=False
Next Fnum
End If
CleanUp:
Application.ScreenUpdating = True
End Sub
---------------------------------------------------------

But the change i've made was to change the part where the VBA copies it into a sheet "after" the last one, to append it to a existing sheet "Totaal".

not working code
---------------------------------------------------------

Sub Example12()
Dim MyPath As String
Dim FilesInPath As String
Dim MyFiles() As String
Dim SourceRcount As Long
Dim Fnum As Long
Dim mybook As Workbook
Dim basebook As Workbook

'Fill in the path\folder where the files are
'on your machine
MyPath = "c:\Data"

'Add a slash at the end if the user forget it
If Right(MyPath, 1) <> "\" Then
MyPath = MyPath & "\"
End If

'If there are no Excel files in the folder exit the sub
FilesInPath = Dir(MyPath & "*.csv")
If FilesInPath = "" Then
MsgBox "No files found"
Exit Sub
End If

On Error GoTo CleanUp

Application.ScreenUpdating = False
Set basebook = ThisWorkbook

'Fill the array(myFiles)with the list of Excel files in the folder
Fnum = 0
Do While FilesInPath <> ""
Fnum = Fnum + 1
ReDim Preserve MyFiles(1 To Fnum)
MyFiles(Fnum) = FilesInPath
FilesInPath = Dir()
Loop

'Loop through all files in the array(myFiles)
If Fnum > 0 Then
For Fnum = LBound(MyFiles) To UBound(MyFiles)
Set mybook = Workbooks.Open(MyPath & MyFiles(Fnum))
mybook.Worksheets(1).Copy

**basebook.Sheets("Totaal").Select
NextRow = Cells(Rows.Count, 0).End(xlUp).Row
Cells(NextRow, 1).Select
ActiveSheet.Paste**

On Error Resume Next
ActiveSheet.Name = mybook.Name
On Error GoTo 0

' You can use this if you want to copy only the values
' With ActiveSheet.UsedRange.Value = .Value
' End With

mybook.Close savechanges:=False
Next Fnum
End If
CleanUp:
Application.ScreenUpdating = True
End Sub

我还没有改变这个的知识:(。我是在正确的轨道上吗？

非常感谢所有输入！

EXTRA INFO：CSV文件中的数据放在第一列。在整个合并过程之后，我计划在之后拆分成列....

谢谢！

Set basebook = ThisWorkbook之后

输入：

Dim nextRow As Integer
Dim wsTotal As Worksheet
Set wsTotal = basebook.Worksheets("Total")

这是更正的For循环：

'Loop through all files in the array(myFiles)
If Fnum > 0 Then
    For Fnum = LBound(MyFiles) To UBound(MyFiles)

        'open file
        Set mybook = Workbooks.Open(MyPath & MyFiles(Fnum))

        With wsTotal

            'activate if you want (optional)
            '.Activate

            'copy all the data on the sheet
            mybook.Worksheets(1).UsedRange.Copy

            'find the next empty row
            nextRow = .Range("A1").SpecialCells(xlCellTypeLastCell).Row + 1

            'select if desired (optional)
            '.Cells(NextRow, 1).Select

            'paste the data
            .Cells(nextRow, 1).PasteSpecial (xlPasteAll)

            'turn off copy mode
            Application.CutCopyMode = False

            'Do you really want to change the worksheet name?
            .Name = mybook.Name
        End With

        'close file
        mybook.Close savechanges:=False

    Next Fnum

要导入csv文件，我建议使用查询而不是打开它们。这样，您还可以在移动中执行数据到列的分割：

Sub ImportToNewWorksheet(ImpFileName as String)
 Dim mySheet As Worksheet
 Set mySheet = ThisWorkbook.Worksheets.Add
 Call ImportFile(ImpFileName, mySheet.Cells(1,1))
End Sub

Sub ImportFile(ImpFileName As String, ImpDest As Range)
 With ImpDest.Worksheet.QueryTables.Add(Connection:= _
  "TEXT;" & ImpFileName, Destination:=ImpDest)
  .Name = "Import"
  .FieldNames = True
  .RowNumbers = False
  .FillAdjacentFormulas = False
  .PreserveFormatting = True
  .RefreshOnFileOpen = False
  .RefreshStyle = xlOverwriteCells
  .SavePassword = False
  .SaveData = True
  .AdjustColumnWidth = True
  .RefreshPeriod = 0
  .TextFilePromptOnRefresh = False
  .TextFilePlatform = 65001
  .TextFileStartRow = 1
  .TextFileParseType = xlDelimited
  .TextFileTextQualifier = xlTextQualifierDoubleQuote
  .TextFileConsecutiveDelimiter = False
  .TextFileTabDelimiter = False
  .TextFileSemicolonDelimiter = False
  .TextFileCommaDelimiter = True
  .TextFileSpaceDelimiter = False
  .TextFileColumnDataTypes = Array(1, 1, 1, 1)
  .TextFileTrailingMinusNumbers = True
  .Refresh BackgroundQuery:=False
 End With

End Sub
