Hallo Raul,

Hier die Version mit Querformat und Tabellenlinien

Public Sub Sheet_in_Word()
    Dim appWord As Word.Application
    Dim doc As Object
    Dim sh As Worksheet
    Set sh = ActiveSheet
    Set appWord = CreateObject(Class:="Word.Application")
    appWord.Visible = True
    sh.Range(sh.PageSetup.PrintArea).Copy
    Set doc = appWord.Documents.Add
    appWord.Activate
    doc.Activate
    appWord.Selection.PasteExcelTable False, False, False
    With appWord.Selection.Tables(1)
        With .Borders(wdBorderLeft)
            .LineStyle = wdLineStyleSingle
            .LineWidth = wdLineWidth050pt
            .Color = wdColorAutomatic
        End With
        With .Borders(wdBorderRight)
            .LineStyle = wdLineStyleSingle
            .LineWidth = wdLineWidth050pt
            .Color = wdColorAutomatic
        End With
        With .Borders(wdBorderTop)
            .LineStyle = wdLineStyleSingle
            .LineWidth = wdLineWidth050pt
            .Color = wdColorAutomatic
        End With
        With .Borders(wdBorderBottom)
            .LineStyle = wdLineStyleSingle
            .LineWidth = wdLineWidth050pt
            .Color = wdColorAutomatic
        End With
        With .Borders(wdBorderHorizontal)
            .LineStyle = wdLineStyleSingle
            .LineWidth = wdLineWidth075pt
            .Color = wdColorAutomatic
