With shortcoder v5+ using WordPress’s custom post type API, the native import/export tools can be used to import and export shortcodes.
Export
All shortcodes in v5+ can be exported using WordPress’s inbuilt exporter tool. It can be found under Tools -> Export. In the export page select "Shortcoder" as the content and download the export file.
The exported file is a XML file in WordPress understandable format and it contains all the shortcode content and its settings. This file can be later used to import in any WordPress site.
Import
The XML file exported in above process has all the shortcoder data and can be imported through WordPress’s own importer plugin. Navigate to Tools -> Import and under WordPress install the importer tool. If it is already installed, run the importer and select the exported XML file.
Import from other sources
