BigQuery, SQL Server, PostgreSQL, Oracle, DuckDB and SQLite. Reads a BigQuery table, or the result of a BigQuery query, into a sheet at a cell you choose. The rows are pulled through the connector, staged into the project database and then put through the SAME import planner a Parquet file goes through — so column types, keep/drop lists, a row filter, deduplication, the write mode (replace, append or upsert on a key), schema-drift handling and the minimum/maximum row guards all mean exactly what they mean for a file. A source row limit is pushed DOWN to BigQuery rather than applied afterwards, which is the difference between scanning a billion rows and not.
