Ottieni la Convalida Cellulare nei File ODS
Con Aspose.Cells for JavaScript via C++, puoi ottenere la convalida applicata a una cella nei file ODS. Per questo, l’API fornisce la proprietà Cell.validation della classe Cell.
Il seguente esempio di codice dimostra l’uso della proprietà Cell.validation caricando il file source ODS e leggendo la validazione della cella A9.
