Souvent, vous devez connaître le numéro de version de l’application qui a créé un document Microsoft Excel. Le Script Aspose.Cells for Java via C++ fournit la propriété Workbook.builtInDocumentProperties à cet effet.
Le code d’exemple suivant montre comment utiliser la propriété Workbook.builtInDocumentProperties. Il charge des fichiers Excel créés avec Microsoft Excel 2003, 2007, 2010 et 2013 et affiche le numéro de version de l’application qui a créé ces documents Excel.
