Tools Export
Exporting your WordPress data (posts, pages, custom post types, comments, custom fields, categories, tags, custom taxonomies, and users) is sometimes necessary and useful. If you are moving to a new host or just want a backup of your site data, then Exporting your site is the answer. Once the export file is created, that file can be used for import by the Tools Import Screen.
The Tools Export Screen is quite simple–just specify the desired Filters, if any, you wish to apply, and then click the Download Export File button to save that file to your local computer.
