Spara varje arbetsblad till en separat PDF fil med JavaScript via C++

Spara varje arbetsblad i en separat PDF-fil

Om du behöver spara varje arbetsblad i din mall-Excel-fil för att generera olika PDF-filer kan du enkelt göra detta. Du kan försöka att ställa in ett arbetsbladsvänteläge till PdfSaveOptions.SheetSet åt gången för att rendera till PDF.
