 def get_properties()

    data_dir = File.dirname(File.dirname(File.dirname(__FILE__))) + '/data/'



    # Instantiating a Workbook object by excel file path

    workbook = Rjb::import('com.aspose.cells.Workbook').new(data_dir + 'Book1.xls')

Ruby-Code

 def add_custom_property()

    data_dir = File.dirname(File.dirname(File.dirname(__FILE__))) + '/data/'



    # Instantiating a Workbook object by excel file path

    workbook = Rjb::import('com.aspose.cells.Workbook').new(data_dir + 'Book1.xls')

    # Retrieve a list of all custom document properties of the Excel file

    custom_properties = workbook.getWorksheets().getCustomDocumentProperties()

    # Adding a custom document property to the Excel file

    custom_properties.add("Publisher", "Aspose")

    # Save the document in PDF format

    workbook.save(data_dir + "Add_Property.xls")

    puts "Added custom property successfully."

end   

Aspose.Cells – Entfernen benutzerdefinierter Eigenschaften

Um benutzerdefinierte Dokumenteigenschaften mit Aspose.Cells Java für Ruby zu entfernen, rufen Sie anremove_custom_property Methode derDokumentieren Modul.

Ruby-Code

 def remove_custom_property()

    data_dir = File.dirname(File.dirname(File.dirname(__FILE__))) + '/data/'



    # Instantiating a Workbook object by excel file path

    workbook = Rjb::import('com.aspose.cells.Workbook').new(data_dir + 'Book1.xls')

    # Retrieve a list of all custom document properties of the Excel file

    custom_properties = workbook.getWorksheets().getCustomDocumentProperties()

    # Adding a custom document property to the Excel file
