These properties can be used to open another file type and then save it in Microsoft Excel 97 format.

NOTE: If you do not want to see each workbook that is opened and closed, add the following line to the beginning of the macro:

   Application.ScreenUpdating = False
				

If you convert a large number of files, this line may cause the macro to appear to stop responding.

The following sample Visual Basic for Applications macro converts the files in a folder and its subfolders:

  Application.ScreenUpdating = False

If you convert a large number of files, this line may cause the macro to
appear to stop responding.

The following sample Visual Basic for Applications macro converts the files
in a folder and its subfolders:

   Sub Converter()

   'Turns off alerts, allows duplicate files to be overwritten without
   prompts
   Application.DisplayAlerts = False

   'Initializes conversion conditions.
   SearchDir = InputBox("Input name of directory to start in")
   FileExt = InputBox("Input extension of files to convert in the form
   *.xxx")
   SaveDir = InputBox("Input name of directory to save files to")
   SearchSubs = MsgBox(prompt:="Do you want to include files in
   subdirectories?", Buttons:=vbYesNo)

   'Initializes the search.
   With Application.FileSearch
       .NewSearch
       .LookIn = SearchDir

   'Determines whether to search subdirectories.
   If SearchSubs = 6 Then
       .SearchSubFolders = True
   Else
       .SearchSubFolders = False
   End If

   'Determines file type to convert.
       .FileName = FileExt
       .MatchTextExactly = True

   'If the search found files, loops again, opens, and then resaves in the
   'Microsoft Excel workbook format
       If .Execute > 0 Then
           counter = 0
           For i = 1 To .FoundFiles.Count
               counter = counter + 1
               Workbooks.Open FileName:=.FoundFiles(i)

   'Builds the new name by deleting the previous extension.
               ActiveWorkbook.SaveAs FileName:=SaveDir & "\" & _
                 Left(ActiveWorkbook.Name, Len(ActiveWorkbook.Name) - 4), _
                 FileFormat:=xlWorkbookNormal
               ActiveWorkbook.Close savechanges:=False
           Next i

   'Returns how many files were converted.
           MsgBox prompt:=counter & " files were converted"
       ElseIf .Execute = 0 then
           MsgBox "No files were found, no files were converted"
       End If

   End With
