This package lets you unload a CSV from a warehouse, turn that CSV into SQL statements creating a temp table and inserting data with a CLI command, and copy those SQL statements into your query editor so you can start using the data in a different warehouse. Useful for when you need to join data together that's stored in two separate data warehouses (e.g. finance and product data).
For small datasets, this is good, but for anything significant, using the database's native bulk load will be more efficient than INSERT statements.
