I guess, Forum2tech is right, you need to insert <br> to have breaks into paragraphs. However, I understand that manually inserting <br> for great amount of products will take too long. So I can offer you the solution using which it is possible to insert paragraphs on a fly right in the process of import without manual work in the file done.
It is possible performing import using Store Manager for Magento application.
Basically you need to run import via Store Manager for Magento and during import use the following expression formula for the description field-
CSV_COL(2) - represents the number of column with description
Also, please, note in case your line breakers are make by some other method than Enter, please, let us know, so we could adjust the expression for you.
