Need to convert the file extension from .xls to .xlsx using batch script

Hi All,

With the help of batch script i can rename the file extension but the original format remains same.Is there any command to open the
(.xls) files automatically from a folder and save it to (.xlsx) format without any manual intervention.

Please suggest.

Nothing built-in. You need to load the file into the application, then save as a different file type. This can be done with Office Automation, using VB Script or PowerShell.
Is it something you have to do a lot and all the time?

I think this might help you: here.

Or just try this:
Sub Convertxlsxlsx()

Dim strCurrentFileExt As String
Dim strNewFileExt As String
Dim objFSO As Object
Dim objFolder As Object
Dim objFile As Object
Dim xlFile As Workbook
Dim strNewName As String
Dim strFolderPath As String

strCurrentFileExt = ".xls"
strNewFileExt = ".xlsx"

strFolderPath = "C:\Users\USER\Downloads\CDS"
If Right(strFolderPath, 1) <> "" Then
strFolderPath = strFolderPath & ""
End If

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.getfolder(strFolderPath)
For Each objFile In objFolder.Files
strNewName = objFile.Name
If Right(strNewName, Len(strCurrentFileExt)) = strCurrentFileExt Then
Set xlFile = Workbooks.Open(objFile.Path, , True)
strNewName = Replace(strNewName, strCurrentFileExt, strNewFileExt)
Application.DisplayAlerts = False
Select Case strNewFileExt
Case ".xlsx"
xlFile.SaveAs strFolderPath & strNewName, XlFileFormat.xlOpenXMLWorkbook
Case ".xlsm"
xlFile.SaveAs strFolderPath & strNewName, XlFileFormat.xlOpenXMLWorkbookMacroEnabled
End Select
Application.DisplayAlerts = True
End If
Next objFile

strCurrentFileExt = vbNullString
strNewFileExt = vbNullString
Set objFSO = Nothing
Set objFolder = Nothing
Set objFile = Nothing
Set xlFile = Nothing
strNewName = vbNullString
strFolderPath = vbNullString

End Sub

Here's a VBS I had provided as answer to an earlier question.  Save as a VBS file, and then run as follows from a command prompt, providing the path of the folder where the XLS file are you want to convert.

cscript yourfilename.vbs "c:\yourfolderpath"

Keep in mind that this saves as an XLSX file, not XLSM, so if any of the XLS files contain macros that could be a problem.

Const xlOpenXMLWorkbook = 51             '(without macro's in 2007-2016, xlsx)
Const xlOpenXMLWorkbookMacroEnabled = 52 '(with or without macro's in 2007-2016, xlsm)
Const xlExcel12 = 50                     '(Excel Binary Workbook in 2007-2016 with or without macro's, xlsb)
Const xlExcel8 =56                       '(97-2003 format in Excel 2007-2016, xls)

' Extensions for old and new files
strOld = "xls"
strNew = "xlsx"

' Set up filesystem object for usage
Set objFSO = CreateObject("Scripting.FileSystemObject")

' Get folder name to process off the command line, make sure it's valid
If (WScript.Arguments.Count > 0) Then
    strFolder = Wscript.Arguments(0)
    If Not objFSO.FolderExists(strFolder) Then
        WScript.StdErr.WriteLine "Specified folder does not exist."
    End If
    WScript.StdErr.WriteLine "No folder name specified to process."
End If

' Access the folder to process
Set objFolder = objFSO.GetFolder(strFolder)

' Load Excel (hidden) for conversions
Set objExcel = CreateObject("Excel.Application")
objExcel.Visible = False
objExcel.DisplayAlerts = False

' Process all files
For Each objFile In objFolder.Files
    ' Get full path to file
    strPath = objFile.Path
    ' Only convert desired files
    If LCase(objFSO.GetExtensionName(strPath)) = LCase(strOld) Then
        ' Display to console each file being converted
        Wscript.Echo "Converting """ & strPath & """"
        ' Load file into Excel and save as new format Excel file
        Set objWorkbook = objExcel.Workbooks.Open(strPath, False, True)
        objWorkbook.SaveAs Replace(strPath, strOld, strNew), xlOpenXMLWorkbook
        objWorkbook.Close False
        Set objWorkbook = Nothing
    End If

'Wrap up
Set objExcel = Nothing
Set objFSO = Nothing

Or you can just used libreoffice --headless, which allows conversion between any of the many formats LibreOffice understands.

I don't consider #a42408753 a suitable solution. Being VBA code, you have to implement that in any Office application, which is much over the top here. Using VBS as in #a42409005 is suitable in general, and I would agree to accept that, as it would work well enough to be useful.

Please provide your recommendations of how you feel this question should be closed. When doing so, be sure to include the CommentID of each comment, as well as a short explanation of why those comments should be considered a solution.
In this case I believe that #a42409005 is the right solution to be accepted.  It meets the authors need and can be easily run in a batch mode as requested by the author.  While #a42408753 is another approach, since it uses a VBA approach it requires manual intervention to execute, and would not match the request for a scripted batch approach as well, for this particular question.

At the end of the day it would be great if the author could revisit and guide the closure property, but without that a moderator will have to make this judgement call.

#a42409005 suggestion is maybe more suitable but #a42408753 suggestion is a possible solution as well.
