Advanced Import: One-Click Demo Import for WordPress

Please make sure it is exported using the Advanced Export plugin

Login to your WordPress dashboard, go to Appearance -> Demo Import.
You can also find Import zip options on the WordPress dashboard -> Tools -> Advanced Import.

If you are providing starter content- NO, but if you are migrating site – Yes. As long as the exported site is live on the internet it is not necessary but if you are migrating the site from local to live you should check it.
Technically, if you check to include media, the zip files content media files. Huge media files may cause other issues. Generally not recommended to check but you can check media as your requirements.

First of all, you need to Export your theme demo data from your live demo site using Advanced Export plugin.
Export the zip file, it should contain 3 files content.json, options.json and widgets.json.
If you are submitting a theme on WordPress dot org, you are not allowed to include Demo files ( XML, JSON, ZIP), You have to create a separate plugin for your theme/company. We would like to highly recommend creating a single plugin for your all themes. For other platforms, you may add code to your theme.
Code Example :

function prefix_demo_import_lists(){    $demo_lists = array(       'demo1' =>array(          'title' => __( 'Title 1', 'text-domain' ),/*Title*/          'is_pro' => false,/*Is Premium*/          'type' => 'gutentor',/*Optional eg gutentor, elementor or other page builders or type*/          'author' => __( 'Gutentor', 'text-domain' ),/*Author Name*/          'keywords' => array( 'medical', 'multipurpose' ),/*Search keyword*/          'categories' => array( 'medical','multipurpose' ),/*Categories*/             'template_url' => array(                 'content' => 'full-url-path/content.json',/*Full URL Path to content.json*/                 'options' => 'full-url-path/master/options.json',/*Full URL Path to options.json*/                 'widgets' => 'full-url-path/widgets.json'/*Full URL Path to widgets.json*/             ),          'screenshot_url' => 'full-url-path/screenshot.png?ver=1.6',/*Full URL Path to demo screenshot image*/          'demo_url' => 'https://www.demo.cosmoswp.com/',/*Full URL Path to Live Demo*/          /* Recommended plugin for this demo */          'plugins' => array(             array(                'name'      => __( 'Gutentor', 'text-domain' ),                'slug'      => 'gutentor',             ),              array(                 'name'      => __( 'your plugin name', 'text-domain' ),                 'slug'      => 'plugin-slug',                 'source'      => 'https://downloads.wordpress.org/plugin/advanced-import.1.4.1.zip', //full url with zip, your theme url, or any site link with zip will work             ),          )       ),         'demo2' =>array(             'title' => __( 'Title 2', 'text-domain' ),/*Title*/             'is_pro' => false,/*Is Premium*/             'type' => 'gutentor',/*Optional eg gutentor, elementor or other page builders or type*/             'author' => __( 'Gutentor', 'text-domain' ),/*Author Name*/             'keywords' => array( 'about-block', 'about 3' ),/*Search keyword*/             'categories' => array( 'contact','multipurpose','woocommerce' ),/*Categories*/             'template_url' => array(                 'content' => 'full-url-path/content.json',/*Full URL Path to content.json*/                 'options' => 'full-url-path/master/options.json',/*Full URL Path to options.json*/                 'widgets' => 'full-url-path/widgets.json'/*Full URL Path to widgets.json*/             ),             'screenshot_url' => 'full-url-path/screenshot.png?ver=1.6',/*Full URL Path to demo screenshot image*/             'demo_url' => 'https://www.demo.cosmoswp.com/',/*Full URL Path to Live Demo*/             /* Recommended plugin for this demo */             'plugins' => array(                 array(                     'name'      => __( 'Gutentor', 'text-domain' ),                     'slug'      => 'gutentor',                 ),                 array(                     'name'      => __( 'Contact Form 7', 'text-domain' ),                     'slug'      => 'contact-form-7',                     'main_file' => 'wp-contact-form-7.php',/*the main plugin file of contact form 7 is different from plugin slug */                 ),             )         ),         'demo3' =>array(             'title' => __( 'Title 1', 'text-domain' ),/*Title*/             'is_pro' => true,/*Is Premium : Support Premium Version*/             'pro_url' => 'https://www.cosmoswp.com/pricing/',/*Premium version/Pricing Url*/             'type' => 'gutentor',/*Optional eg gutentor, elementor or other page builders or type*/             'author' => __( 'Gutentor', 'text-domain' ),/*Author Name*/             'keywords' => array( 'woocommerce', 'shop' ),/*Search keyword*/             'categories' => array( 'woocommerce','multipurpose' ),/*Categories*/             'template_url' => array(/* Optional for premium theme, you can add your own logic by hook*/                 'content' => 'full-url-path/content.json',/*Full URL Path to content.json*/                 'options' => 'full-url-path/master/options.json',/*Full URL Path to options.json*/                 'widgets' => 'full-url-path/widgets.json'/*Full URL Path to widgets.json*/             ),             'screenshot_url' => 'full-url-path/screenshot.png?ver=1.6',/*Full URL Path to demo screenshot image*/             'demo_url' => 'https://www.demo.cosmoswp.com/',/*Full URL Path to Live Demo*/             /* Recommended plugin for this demo */             'plugins' => array(                 array(                     'name'      => __( 'Gutentor', 'text-domain' ),                     'slug'      => 'gutentor',                 ),             )         ),         /*and so on ............................*/    );    return $demo_lists; } add_filter('advanced_import_demo_lists','prefix_demo_import_lists');
