Changes to Bulk Edit/Upload, what do i do now?

I’ve just gone to do a bulk edit via feed but it seems there is no option to do that anymore. AI tells me they have removed the feature and that I basically need coding knowledge to bulk edit now or use a third party tool. Is this correct?

If so, does anyone know what the easiest way to do this now is please? I have a couple hundred listings to edit and I need to edit a just a few words in the bullet points and descriptions.
