Por defecto, Aspose.Cells guarda todas las hojas visibles de un libro en un archivo PDF. Con la opción PdfSaveOptions.sheetSet, puedes guardar hojas específicas en un archivo PDF. Por ejemplo, puedes guardar la hoja activa en PDF, guardar todas las hojas (tanto visibles como ocultas) en PDF, guardar varias hojas personalizadas en PDF.
Guardar Hoja de Cálculo Activa en PDF
Si solo quieres exportar la hoja activa a PDF, puedes lograrlo pasando SheetSet.active a la opción PdfSaveOptions.sheetSet.
La hoja Sheet2 es la hoja activa del archivo fuente sheetset-example.xlsx.

Guardar todas las hojas en PDF
SheetSet.visible indica hojas visibles en un libro, y SheetSet.all indica todas las hojas, incluyendo las hojas visibles e invisibles en un libro. Si desea exportar todas las hojas a PDF, simplemente pase la opción de SheetSet.all a PdfSaveOptions.sheetSet.
El archivo fuente ejemplo-de-conjunto-de-hojas.xlsx contiene las cuatro hojas con la hoja oculta ‘Sheet3’.

Si su hoja de cálculo contiene fórmulas, es mejor llamar a Workbook.calculateFormula() justo antes de renderizar la hoja de cálculo en formato PDF. Al hacerlo, se asegurará de que los valores dependientes de las fórmulas se recalculen y los valores correctos se muestren en el PDF.
