Bulk Editing Product Meta Tags

I am wondering if there is any way to edit/add/remove PRODUCT meta tags by bulk or folder. Just so no one misunderstands, I mean the product meta tags which are edited through the admin > catalog > products - where there is an orange or black symbol on the right of the product.

I want to remove meta tags from a bunch of my products. Since it would be extremely time-consuming to do each one, I wonder if anyone knows an add-on or some way to do this by bulk.

Thanks

MOST IMPORTANTLY, you need to upgrade your site to a secure version of the software.

Then, once you've done that, you can study the code in the admin PHP files to understand what it does with the database when editing/updating metatag data, and build your own means of managing that data in bulk.

But you really owe it to yourself and your customers to upgrade your site first.
