Change font size in php csv output

Question

I have no idea how to change the font size for a specific code, since it has no echo etc. This is a module in Prestashop 1.5 and its php. All text in the code below should be font size 18, currently its 10..

    $addressdata .= ''.chr(13).chr(13);
        $addressdata .= utf8_encode((strlen(str_replace('-','',$address->company))>0 ? $address->company.chr(13) : ''));
        $addressdata .= utf8_encode($address->firstname.' '.$address->lastname.chr(13));
        $addressdata .= utf8_encode($address->address1.chr(13));
        $addressdata .= utf8_encode((strlen(str_replace('-','',$address->address2))>0 ? $address->address2.chr(13) : ''));
        $addressdata .= utf8_encode($address->postcode.' '.$address->city.chr(13));
        $addressdata .= $this->getCountryName($address->id_country, $order->id_lang).chr(13).chr(13);
        $addressdata .= ''.chr(13).chr(13);

You can not do formatting with CSV (font-size, color, etc ...). If you want to do the formatting you can use this biletec to generate XLS https://phpexcel.codeplex.com/
