what does it do? - This module allows users to export nodes and then import it into another Drupal installation, or on the same site. This module can help to save a lot of time that is usually spent setting up new websites that have similar nodes to websites you've already made, migrating nodes to new Drupal versions, or between development/staging/production sites. The same content types need to be created before the imports will work.
