There are 2 online store sites on different engines and different topics.
The first online store on ShopOS already contains the catalog structure and all the necessary additional fields. Each section has a Word file. Each Word file contains about 100 products with 2-3 pictures.
The second online store on Joomla is completely empty. It only costs the engine, design and standard settings of the online store. You need to create sections (about 20 sections), all the parameters of goods and throw goods from Exel (without pictures). It's 500 products.
