Displaying All WooCommerce Products on Admin Products Page
By default, the Products section in WooCommerce only displays 20 products per page. This means that making edits to a bunch of products will require a reload by moving to page 2, 3, 4, etc. These reloads can really increase your work time. There’s a simple trick to display ALL of your products on one page, preventing the need for moving through paginated products.
Display ALL WooCommerce Products
When in your wp-admin, navigate to the WooCommerce Products page. From there, click on the Screen Options dropdown in the top-right corner of your screen. This WooCommerce specific Screen Options panel will have an option to set the number of products display per page. Simply set this number to a high number to display all of your products. Obviously, if the number is greater than the number of WooCommerce products you have available, they will all be displayed. You can set this number to whatever you want.
