I need a tool to convert MS Word & MS Excel files to new 2013 version

I'm looking for a tool to convert MS Word (.doc) to .docx and MS Excel (.xls) to .xlsx - has anyone got any experience of this. I need to do a few thousand at once.

Don't understand your question

if you have .doc and .xls files this means they are in Office 2003 and earlier if you want them to be converted to .docx and .xlsx meaning to 2007 later versions then simply open blank Word or Excel new version and from the File Open menu choose your .doc or .xls file and choose Save as and make sure in the file type to choose the new .docx or .xlsx type and here you go they are converted.

I haven't used it myself, but Office Migration Planning Manager of http://www.microsoft.com/en-us/download/details.aspx?id=11454 contains a tool called OFC.exe to perform bulk converts. You'll have to edit OFC.INI to contain all necessary folders and settings, and then up you go. For a short usage example see http://blogs.msdn.com/b/ericwhite/archive/2008/09/19/bulk-convert-doc-to-docx.aspx.

To add to the above comment you would be creating a new file for each of these dated Office file.
This would give them all new Time Stamps and you would have duplicate files.

It does mot hurt to have the old files remain as they are (2003 format) and moving forward all new files will be using the *.DOCX or *.XLSX.  

Office 2013 can read 2003 files perfectly fine.

If you did want to do something you could script something like powershell, but I think it is a waste of time and effort.

I don't know if the Tools takes over the creation and modification time stamps of the original file. If not, PowerShell can be applied after the fact.
you can automate the process with a macro e.g. as . Put all the documents that you wish to convert into a folder and run the macro. Select the folder you have used to store the documents. Note that the macro as written will not work with password protected documents.
Sub SaveAllAsDOCX()
Dim strFilename As String
Dim strDocName As String
Dim strPath As String
Dim oDoc As Document
Dim fDialog As FileDialog
Dim intPos As Integer
Set fDialog = Application.FileDialog(msoFileDialogFolderPicker)
With fDialog
    .Title = "Select folder and click OK"
    .AllowMultiSelect = False
    ..InitialView = msoFileDialogViewList
    If .Show <> -1 Then
        MsgBox "Cancelled By User", , "List Folder Contents"
        Exit Sub
    End If
    strPath = fDialog.SelectedItems.Item(1)
    If Right(strPath, 1) <> "\" Then strPath = strPath + "\"
End With
If Documents.Count > 0 Then
    Documents.Close SaveChanges:=wdPromptToSaveChanges
End If
If Left(strPath, 1) = Chr(34) Then
    strPath = Mid(strPath, 2, Len(strPath) - 2)
End If
strFilename = Dir$(strPath & "*.doc")
While Len(strFilename) <> 0
    Set oDoc = Documents.Open(strPath & strFilename)
    strDocName = ActiveDocument.FullName
    intPos = InStrRev(strDocName, ".")
    strDocName = Left(strDocName, intPos - 1)
    strDocName = strDocName & ".docx"
    oDoc.SaveAs FileName:=strDocName, _
    oDoc.Close SaveChanges:=wdDoNotSaveChanges
    strFilename = Dir$()
End Sub
