Query about CSV File Conversion into another workbook

This is a working program for conversion of CSV file into tabled excel file. My question is how can this be modified and order the program to process the csv file into another workbook bec. in the codes below, the code processes the csv file into Sheet2. Thank you



Option Explicit

Sub ImportFile()
Dim sPath As String
Dim intChoice As Integer
Dim strPath As String
Dim FilePath As String

'change the display name of the open file dialog
Application.FileDialog(msoFileDialogOpen).Title = _
"CSV File Opener"

'Remove all other filters
Call Application.FileDialog(msoFileDialogOpen).Filters.Clear

'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,
'is in the same folder as the workbook. If
'you want something more flexible, you can
'use Application.GetOpenFilename to get a
'file open dialogue that returns the name
'of the selected file.
'On the page Fast text file import
'I show how to do that - just replace the
'file pattern "txt" with "csv".
sPath = strPath

'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.
copyDataFromCsvFileToSheet sPath, ";", "Sheet2"

End Sub
