Can I use CSV Import for any component?
No, CSV Import is only able to import standard Joomla article fields and JReviews custom fields.
Do I need JReviews to use CSV Import
No, in fact CSV Import is a great tool to import thousands for Joomla articles quickly.
Is CSV Import encoded?
No, once purchased you get access to the source code which you are free to modify. However, the license for CSV Import is per domain, so you do need to purchase one license for each domain.
