By default, X-Cart allows importing the following data:
Products (with or without information on product classes and attributes);
X-Cart add-ons installed in your store can extend the default type list for data import.
The Orders Import add-on allows you to import the "Orders" data type.
The Product Reviews add-on allows importing the "Reviews" data type.
The Newsletter Subscriptions add-on allows importing the "Subscribers" data type.
The Make/Model/Year add-on - the "Products with Make/Model/Year/Engine" and "Make/Model/Year/Engine" listing data types.
Each data type will require an import file of a special format.
products.csv - allows importing products and all related data. The default set of fields can be extended. See CSV Import: Products for more info.
attributes.csv - allows importing product classes and attributes as database entities. Using this file, a store admin can create attributes of different types and populate a store with them. The file doesn't allow assigning attributes to products. See CSV Import: Classes & Attributes for more info.
product-attributes.csv - allows importing product classes and attributes and assigning them to products and can substitute a products.csv file if only the attributes data needs an update. See CSV Import: Product Attribute Values for more info.

If you decide to import data into X-Cart and do not wish to update specific fields during the import process, you should not include these fields in your CSV file for import. Instead, remove the respective column(s) from the file.
