@TamaHelp If you are open to using apps, then you sure can easily bulk delete Products with Excelify.
The process is quite simple, you can export your Products using Excelify app and export only Basic Columns.
You can also click on the "Filters" button to export only specific items not all. As if you do not wish to update other items then you do not need to include those in the file.
In the exported file you would have the "Command" column. In this column set value to "DELETE" for any Products, you wish to delete. Then import the file back into Shopify with Excelify and Those Products will get deleted.
You can also use Shopify exported file and just add the "Command" column to the file. The app will be able to find existing Product and delete it by "Handle" as they are always unique in Shopify.
Here we also do have a great tutorial on how to bulk delete Products in Shopify.
