The Total Import PRO allows the import of attribute groups, names and values. It provides full support for the OpenCart attribute entity.
The field name (the XML tag or CSV column heading that you mapped at Step 4) will be used for the Attribute name, and the value in the field for each product will be used for the Attribute value. If you wish to import a particular attribute structure including attribute group you can do this by using a ':' separated list in your attribute field. This is then formatted as follows:
The Total Import PRO creates the appropriate attribute group, attribute name and attribute value.
Here is an example that will create an Attribute Group called "CPU", with an Attribute called "Speed", and will add the attribute to the product with value "1.6GHz".
