`sq` is a swiss army knife for data. `sq` provides uniform access to
structured data sources like traditional SQL-style databases,
or document formats such as CSV or Excel. `sq` can perform cross-source joins, execute database-native SQL, and output to a multitude of formats including JSON, Excel, CSV, HTML markdown and XML, or output directly to a SQL database. `sq` can inspect sources to see metadata about the source structure (tables, columns, size) and has commands for frequent database operations such as copying or dropping tables.
