这是一个将CSV文件转换为tabled excel文件的工作程序。我的问题是如何修改它并命令程序将csv文件处理成另一个工作簿。在下面的代码中,代码将csv文件处理为Sheet2。谢谢

Option Explicit

'Add a custom filter
Call Application.FileDialog(msoFileDialogOpen).Filters.Add( _
    "CSV Files Only", "*.csv")

'only allow the user to select one file
Application.FileDialog(msoFileDialogOpen).AllowMultiSelect = False

'make the file dialog visible to the user
intChoice = Application.FileDialog(msoFileDialogOpen).Show

If intChoice <> 0 Then

    'get the file path selected by the user
    strPath = Application.FileDialog( _
        msoFileDialogOpen).SelectedItems(1)

    Cells(7, 7) = strPath
Else
    MsgBox "Wrong CSV File. Please Choose Again"

End If
'Below we assume that the file, csvtest.csv,

'you want something more flexible, you can

'file open dialogue that returns the name

'On the page Fast text file import

sPath = strPath

'Procedure call. Semicolon is defined as separator,

再次,对不起,家里没有Excel。问题是copyDataFromCsvFileToSheet。需要重新编写它以创建带有工作表的工作簿或接受带有工作表作为参数的工作簿。它正在做的只是保存到当前的工作簿。尝试更改此部分:

'Procedure call. Semicolon is defined as separator,
'and data is to be inserted on "Sheet2".
'Of course you could also read the separator
'and sheet name from the worksheet or an input
'box. There are several options.

'create a workbook object
dim wb as workbook
'create a new workbook
set wb = workbooks.add
copyDataFromCsvFileToSheet sPath, ";", wb
set wb = nothing

End Sub
'**************************************************************
Private Sub copyDataFromCsvFileToSheet(parFileName As String, _
parDelimiter As String, wb as workbook)

Dim Data As Variant  'Array for the file values

'Function call - the file is read into the array
Data = getDataFromFile(parFileName, parDelimiter)

'If the array isn't empty it is inserted into
'the sheet in one swift operation.
If Not isArrayEmpty(Data) Then
  'If you want to operate directly on the array,
  'you can leave out the following lines.
  With wb.worksheets("Sheet1")
    'Delete any old content
    .Cells.ClearContents
    'A range gets the same dimensions as the array
    'and the array values are inserted in one operation.
    .Cells(1, 1).Resize(UBound(Data, 1), UBound(Data, 2)) = Data
    wb.saveas Filename:="whateveryouwant.xlsx"
  End With
End If



End Sub
