How can I arrange imported products to new categories

[Alibaba]

Hi,

I have 1500 products imported to prestashop site but I have changed the categories. I would like to ask if there is a way to order products' categories by 100 products per change to new categories without using any modules.

I do not want to make that arrangement one by one or reimport by arranging on csv file.

Thanks,

Let me clear my question, I would like to list my products by name or category and I want to change their subcategory totally to the new category I added for new.

So is there a way to do it?
