Excel a trouvé du contenu illisible dans *.xlsx

Je suis en train de travailler sur la génération d'un modèle excel à partir du code. Quand je lance la pièce pour créer mon Classeur, je n'ai pas d'erreurs dans le code, mais quand je suis aller pour ouvrir le document Excel, j'obtiens un message d'erreur indiquant que le fichier est illisible. Je suis en mesure de cliquer pour l'ouvrir de toute façon, et je reçois le message suivant

Supprimé des Enregistrements: Feuille de calcul des propriétés de /xl/workbook.xml partie (Classeur)

Une idée de ce qui ne va pas dans mon code s'il vous plaît?
