Utilizzare WordArt per aggiungere effetti speciali di testo o immagine ai fogli di calcolo. Ad esempio, allungare un titolo lungo la parte superiore del file, decorare il testo e farlo adattare a una forma predefinita, oppure applicare del testo a un foglio di Excel come filigrana di sfondo. Il WordArt diventa un oggetto che puoi spostare o posizionare nei fogli di calcolo per aggiungere decorazioni.
