Convert WordPress posts to products in WooCommerce

Is there anyway I could convert all the posts e have right now on our WordPress install into products using some MySQL query or something like that?

You could install the Post Type Switcher plugin

Or Run SQL query on your database to change the post to product post type

UPDATE  `wp_posts` SET  `post_type` =  'product' WHERE  `post_type` = 'post';

Backup your DB 1st.

UPDATE  `wp_posts` SET  `post_type` =  'wpsc-product' WHERE  `post_type` = 'post';
