A few days back, we announced that how you can generate a data entity using an existing excel sheet which auto generates the metadata of ten entity and also imports any existing records. Here is a reference to that blog post.
However once the entity has been generated in development environment using Excel or other formats, it has to be moved to staging and production environment as well using the inbuilt tooling within Data Entities module.
When import and export options for Data Entities were first introduced two years ago, it working at a single entity level. Today I am pleased to introduced the next logical enhancements. AgilePoint NX v8.0 will start supporting bulk export and import operations.
The same concept has been applied to Picklists as well.
