Hi there ,

Thanks for reaching out!

You can update the value of all items in a category at once using the ‘Bulk Edit’ feature. Here’s how to do it:

1. Go to your WooCommerce dashboard and click on ‘Products’.
2. Filter your products by the category you want to update.
3. Select all the products. You can do this by checking the box at the top of the product list.
4. From the ‘Bulk Actions’ drop-down, select ‘Edit’ and hit ‘Apply’.
5. A window will open where you can make your changes. Select Price and choose change to. Once done, click ‘Update’.

Please note that this will apply the same value to all selected products.

If you have any other questions or need further assistance, feel free to ask.
