This is truly brilliant. I would struggle to name a more impressive piece of recent software. There are so many user cases for this but one of the primary ones is for ETL. Import the data (from file, url etc) into duckdb, quickly enrich it using its amazing sql and analytical prowess, and then export the data to a modern format file or data store. Quite frankly, its user-friendly version of SQL embarrasses the likes of SQL Server and Oracle.
