Node export 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.
Requirements
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.
Node Export + Features Integration
Node Export provides integration with the Feature module. You can export a bundle of nodes and store them in a feature, which can then be installed on another site.
This is a simple way to stage content between two development environments. Another use case is giving your site to a client to have them input content, then moving that content back into your development environment.
Known Issues
Warning: If your site has a lot of content, the node_export_feature list under features could become quite large and break. To resolve this problem, please visit this issue for a work around:
