Almost every relational/SQL database supports JSON natively by now. In case of PostgreSQL you can even choose between raw data dumping JSON with slow lookup or parsed JSONB with fast lookup, see https://www.postgresql.org/docs/current/static/datatype-json.html https://www.postgresql.org/docs/current/static/datatype-json... From there you can extract data into relational tables and dig into 40+ years of SQL knowledge/tools for complex cross table analysing/manipulating/exporting/etc. If you don't need this, fine. Nobody forces you. There are some cases like Let's Encrypt where a dumb, fast schema-less datastore makes sense.
