The plugin uses CSV format for all exports and imports.
Yes, the plugin can download and import media files referenced in the imported content. Media library can also be exported and imported as attachment post type.
Yes, both Gutenberg and Classic editors are supported, but there is no support for plugins like Elementor, WPBakery or any other custom page builders for now.
Yes, it is safe. The plugin includes robust data validation mechanisms to ensure consistency between exported and imported data. Moreover, there is a "Test mode" option that lets you preview the import results without making any actual changes to your site. However, it is always a good practice to create backups before performing any imports to safeguard your data. Additionally, before performing a bulk import, it's recommended to export and import a single item to ensure the process works as expected.
If the export or import didn’t work as expected, you can contact me at kovalchik888@gmail.com for assistance. I’ll be happy to help resolve any issues you encounter.
