Das folgende Makro erstellt aus einer Excel-Tabelle zeilenweise Folien in PowerPoint.

Aufgabe: Aus den Zeilen einer Excel-Tabelle sollen einzelne Folien einer PowerPoint Präsentation erstellt werden.


Vorgehen

  • Erstellen einer neuen PowerPoint-Präsentation
  • Das Makro mit Hilfe der Entwicklertools in die Präsentation einfügen und starten.
    • Makro CreateLayoutFromExcel ausführen, um ein CustomLayout aus der ersten Tabelle der Excel-Datei zu erzeugen
    • Makro CreateSlidesFromExcel ausführen, um die Slides aus der ersten Tabelle der Excel-Dateizu erstellen
  • Anschließend kann die Layout-Folie verschönert werden. Die Änderungen der Layout-Folie werden für alle Folien übernommen, so dass die Folien einheitlich gestaltet sind.
  • Bei Änderungen der Excel-Tabelle müssen noch alle Folien gelöscht und mit dem Makro neu erstellt werden.

Custom Ribbon

Um die Makros über Buttons in einem Ribbon aufrufen zu können, muss die Datei cutomUI.xml in der PPTM im Ornder customUI gespecihert werden. Dies geht am besten über 7z (oder einem anderen Packer).

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">
<ribbon>
<tabs>
<tab id="mxExcelTools" label="Excel Tools">
<group id="customGroup1" label="Excel to PowerPoint">
  <button id="myCreateLayout" visible="true" size="large" label="Create Layout" imageMso="SlideLayoutGallery" onAction="CreateLayoutFromExcel" 
     screentip="Layout erstellen"
     supertip="Erstellt ein Layout aus den Wspalten der ersten Tabelle einer Excel-Datei. Beschriftungen aus der ersten Zeile."
/>
  <button id="myCreateSlides" visible="true" size="large" label="Create Slides" imageMso="SlideNewGallery" onAction="CreateSlidesFromExcel" 
     screentip="Folien erstellen"
     supertip="Erstellt Folien aus den Zeilen aus der ersten Tabelle einer Excel-Datei"

/>
</group>
</tab>
</tabs>
</ribbon>
</customUI>

Die Datei .rels im Ordner _rels muss um den Eintrag:

<Relationship Id="rId9" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/custom-properties" Target="docProps/custom.xml"/>

ergänzt werden. Wichtig ist dabei eine eindeutige id=rId<n>. Z.B. so:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
