Multi-Product Adder and Categorizer
This utility can be used to speed up adding new products to your catalog system. You prepare the data, it will prepare SQL queries that will insert your data into the correct table.
The most important concept of this utility:
This is only a quick get-it-in-there utility. It does not do anything with options, subcategories, or anything else. It is only a way to quickly get a lot of products into the catalog quickly. You should use the Admin features to modify the products once they're in the database.
Note: This utility is in beta.
