Doing some quick research, came across the following VBA code --- I DO NOT take credit for this. I did however changed the DoWork method to add: .Worksheets(1).Range("A1").NumberFormat = "Number"

Sub ProcessFiles()
    Dim Filename, Pathname As String
    Dim wb As Workbook

    Pathname = ActiveWorkbook.Path & "\Files\"
    Filename = Dir(Pathname & "*.xls")
    Do While Filename <> ""
        Set wb = Workbooks.Open(Pathname & Filename)
        DoWork wb
        wb.Close SaveChanges:=True
        Filename = Dir()
    Loop
End Sub

Sub DoWork(wb As Workbook)
    With wb
        'Do your work here
        .Worksheets(1).Range("A1").NumberFormat = "Number"
    End With
End Sub
