Content JSON import/export.
UmContent is a free, simple plugin which allows you to select content nodes and export them to JSON. After you can choose the parent node and restore content from the chosen JSON file. UmContent can be useful for move Umbraco content from development to staging/production servers.
* - UmContent does not change document types structure so you must have identical structure on both environments. You can use uSync to get same document types structure.
