Bulkify applies changes across many products in one collection per job, without editing each product separately in Admin. You select the collection, choose product and variant fields to update, and optionally limit which products are included by status, vendor, product type, or tags. You can preview changes, export a before-and-after spreadsheet, run the job immediately or schedule it, and view status in your job history. Certain completed jobs can be reverted to restore earlier values.
