Renvoie les données de cet objet sous forme de blob converti au type de contenu spécifié. Cette méthode ajoute l'extension appropriée au nom de fichier (par exemple, "monfichier.pdf"). Toutefois, il suppose que la partie du nom de fichier qui suit le dernier point (le cas échéant) est une extension existante qui doit être remplacée. Par conséquent, "ShoppingList.12.25.2014" devient "ShoppingList.12.25.pdf".
Pour afficher les quotas quotidiens pour les conversions, consultez la section Quotas pour les services Google. Les nouveaux domaines Google Workspace peuvent être temporairement soumis à des quotas plus stricts.

Type MIME vers lequel effectuer la conversion. Pour la plupart des blobs, 'application/pdf' est la seule option valide. Pour les images au format BMP, GIF, JPEG ou PNG, les valeurs 'image/bmp', 'image/gif', 'image/jpeg' ou 'image/png' sont également valides. Pour un document Google Docs, 'text/markdown' est également valide.
Définit le type de contenu des octets de ce blob en fonction de l'extension du fichier. La valeur contentType est null si elle ne peut pas être devinée à partir de l'extension.
