Product Loader uploads a data file that contains one line per product in your catalog. Each line has fields corresponding to a subset of the columns in the ec_products table. The first line of the data file is a header that defines which fields are being loaded and the order that they appear in the data file. The remaining lines contain the product data.
Product Extras Loader is similar to the product loader except it loads data into ec_custom_product_field_values, the table which contains the values for each product of the custom fields you have added. The file format resembles the products import data file format.
Product Category Map Loader By Name-Matching creates the mappings between products in ec_products table and categories in ec_categories, ec_subcategories, and ec_subsubcategories tables by inserting rows into ec_category_product_map and ec_subcategory_product_map.) The data file you create for uploading should consist of product sku and category or subcategory names, one per row. This process attempts to be smart by using the SQL "LIKE" function to resolve close matches between categories listed in the data file and those known in the database.
Product Category Map Loader By Index Matching creates the product-categories mappings by finding exact matches to the category tables' indexes category_id, subcategory_id, subsubcategory_id.
Bulk Product Image Loader imports product images for existing products, and creates thumbnails for them. Place product images in a set of directories accessible by this server. Then use this utility to upload a file that maps product sku to the location of the product images full_imagepathname.
