To upload a file containing entities simply click on the 3 dots menu next to the create entity button and then click upload entities.
You can upload entities in either JSON or YAML format.
Before uploading, you need to decide if the new file you are uploading should REPLACE or MERGE with the existing entities.
If you choose to REPLACE, all existing entities will be deleted and replace with the entities in the file you are uploading.
If you choose to MERGE, only the entities that are not in the system will be saved while the others will be discarded to avoid duplication.
NOTE: if you are working with a large number of custom entities, we recommend to download the complete list of entities (explained here), perform your changes at scale in the file, then re-upload using the replace option. This will allow you to keep locally a record of the different datasets of entities you are have created.
