The scenario is I crawled data from wikipedia and some entities have different properties, even though they are in the same type, i.e. the same neo4j label. In this case, the data is in the json format, not excel, and most importantly, it's infeasible to decide a set of properties given an entity.
Is it possible to create neo4j database without a fixed set of entity properties defined beforehand? The number of properties will depend on a particular data instance.
