This module allows users to export nodes and then import it into another Drupal installation, or on the same site. Using this module you can save yourself a lot of time 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. You will need the same content types for the imports to work (unless using Feeds to import), and ideally relevant compatibility with fields, and modules.
