]
Par défaut, Aspose.Cells enregistre toutes les feuilles visibles d’un classeur dans un fichier PDF. Avec l’option PdfSaveOptions.sheetSet, vous pouvez enregistrer des feuilles spécifiques dans un PDF, par exemple, vous pouvez enregistrer la feuille active en PDF, enregistrer toutes les feuilles (visible et cachées) en PDF, ou enregistrer des feuilles multiples personnalisées en PDF.
Enregistrer la feuille de calcul active en PDF
Si vous souhaitez uniquement exporter la feuille active en PDF, vous pouvez le faire en passant SheetSet.active à l’option PdfSaveOptions.sheetSet.
La feuille Sheet2 est la feuille active du fichier source sheetset-example.xlsx.

Tout enregistrer en PDF
SheetSet.visible indique les feuilles visibles dans un classeur, et SheetSet.all indique toutes les feuilles y compris les feuilles visibles et cachées/invisibles. Si vous souhaitez exporter toutes les feuilles en PDF, vous pouvez simplement passer SheetSet.all à l’option PdfSaveOptions.sheetSet.
Le fichier source sheetset-example.xlsx contient les quatre feuilles avec la feuille cachée Sheet3.

Si votre feuille de calcul contient des formules, il est préférable d’appeler Workbook.calculateFormula() juste avant de rendre la feuille de calcul au format PDF. Cela garantira que les valeurs dépendant des formules sont recalculées et que les valeurs correctes sont rendues dans le PDF.
