Liste, ändern oder löschen externe Formel Verweise (Links) mit VBA in Microsoft Excel
Mit den folgenden Makros können Sie Formeln in Zellen finden und löschen, die auf andere Arbeitsmappen verweisen.
Die Makros finden nicht alle externen Referenzen, da sie nur in den Arbeitsblattformeln angezeigt werden.
