In Microsoft Excel 2000, the
Application object has
FileSearch and
FoundFiles properties that return an object containing the list of files found in the search. These properties can be used to open another file type and then save it in Excel 2000 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:
Sub Converter()
'Turns off alerts, allows duplicate files to be overwritten without prompts
Application.DisplayAlerts = False
MsgBox "The Macro will ask you to input the name of the directory" & _
" to start in and the name of the directory to save files to." & _
" These directories must already exist or the Macro will fail." & _
" For example, use c:\My documents\start and c:\My documents\copy" & _
" as Names of your directories to start in and copy to."
'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
End Sub
