You’ve added your products to your store and realize they are now a LOT!! WooCommerce allows you to edit some areas of these products all at once!!
Access your list of products
There are checkboxes on the left side of all of your products. You can either select products by clicking on the boxes individually, or by selecting the checkbox on the header row (row containing: Name, SKU, Stock, Price, Categories etc.)
Select bulk by category
Click on any one category in your product list to allow only items in that category to appear! Then, if you’d like to edit all the products in that category, select the checkbox on the header row!
NB: Removing a product from a category does not usually work well using this method. To remove an item from a category – you may need to remove it per product, rather than in Bulk Selection.

Bulk Editing Fields
Below are the default WooCommerce fields one might encounter, although when certain extensions are active, additional fields might also be present.

Bulk Editing Limitations
Bulk editing works best with Simple products, and cannot edit the complexities of variable, grouped, or other complicated products.
Bulk editing can only be applied to products that are visible and can be ticked for inclusion in a bulk editing session.
