I am writing to seek some help in creating a outlook macro, which is able extract all xls attachment files into one excel workbook (save each attachment in individual worksheet) from specific outlook folder called ‘data’, which is sub-folder under the Inbox folder. 

Sub GetAttachments()
On Error Resume Next
'create the folder if it doesnt exists:
    Dim fso, ttxtfile, txtfile, WheretosaveFolder
    Dim objFolders As Object
    Set objFolders = CreateObject("WScript.Shell").SpecialFolders
 
    'MsgBox objFolders("mydocuments")
    ttxtfile = objFolders("mydocuments")
    
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set txtfile = fso.CreateFolder(ttxtfile & "\Email Attachments")
    Set fso = Nothing
    
    WheretosaveFolder = ttxtfile & "\Email Attachments"
    
On Error GoTo GetAttachments_err
' Declare variables
    Dim ns As NameSpace
    Dim Inbox As MAPIFolder
    Dim Item As Object
    Dim Atmt As Attachment
    Dim FileName As String
    Dim i As Integer
    Set ns = GetNamespace("MAPI")
    'Set Inbox = ns.GetDefaultFolder(olFolderInbox)
    ' added the option to select whic folder to export
    Set Inbox = ns.PickFolder
    
    'to handle if the use cancalled folder selection
    If Inbox Is Nothing Then
                MsgBox "You need to select a folder in order to save the attachments", vbCritical, _
               "Export - Not Found"
        Exit Sub
    End If


    i = 0
' Check Inbox for messages and exit of none found
    If Inbox.Items.Count = 0 Then
        MsgBox "There are no messages in the selected folder.", vbInformation, _
               "Export - Not Found"
        Exit Sub
    End If
' Check each message for attachments
    For Each Item In Inbox.Items
' Save any attachments found
        For Each Atmt In Item.Attachments
        ' This path must exist! Change folder name as necessary.
           'FileName = "C:\Email Attachments\" & Atmt.FileName
           'if want to add a filter:
           'If Right(Atmt.FileName, 3) = "xls" Then
            
           FileName = WheretosaveFolder & "\" & Atmt.FileName
            Atmt.SaveAsFile FileName
            i = i + 1
         Next Atmt
    Next Item

        MsgBox "There were " & i & " attached files." _
        & vbCrLf & "These have been saved to the Email Attachments folder in My Documents." _
        & vbCrLf & vbCrLf & "Thank you for using Liron Segev - TheTechieGuy's utility", vbInformation, "Export Complete"
    Else
        MsgBox "There were no attachments found in any mails.", vbInformation, "Export - Not Found"
    End If
' Clear memory
GetAttachments_exit:
    Set Atmt = Nothing
    Set Item = Nothing
    Set ns = Nothing
    Exit Sub
' Handle errors
GetAttachments_err:
    MsgBox "An unexpected error has occurred." _
        & vbCrLf & "Please note and report the following information." _

        , vbCritical, "Error!"
    Resume GetAttachments_exit
End Sub
I manage to find the following code for excel attachment extraction, but currently struggling to get it to work. Any further assistance would be very much appreciated.

Many thanks
