Hi,
You could use a mass action.
In the menu System>Mass actions, create a new one with an action "display the results" and select the "product_name" column.
This will display a list of the products (you might need to add a filter to do that one category at a time to avoid the page crashing if there are too many products). In that list, you can double click on the product name to edit it and then validate.
Also, you can use the export action of a mass action to export the product data. And with it, you can select the columns you want in the CSV. That way, you could have only the product_id and product_name.
