Edit: En respuesta a cali, el procedimiento para aplicar el codigo es crear un macro en excel, para esto tecleamos Alt+F8, se abre una ventana y le asignamos un nombre x para crear un nuevo macro y le damos click en el boton de 'create', borramos lo que excel nos pone por default y le metemos el codigo de arriba, presionamos F5 para que excel corra el codigo y nos arroje el flash para poder grabarlo por separado =)
