I need a small, reliable script that pulls numerical data from my existing SQL database and feeds it into a clean, ready-to-use format for downstream processing. The job is straightforward: connect to the SQL instance, select the relevant tables or views, transform the figures only if absolutely necessary (simple type casting or column renaming), and export or forward the result exactly as specified—CSV, JSON, or a direct push into another service once we agree on the target. Please make the solution lightweight, well-commented, and easy for me to schedule or rerun. A quick read-me that outlines connection parameters, configurable variables, and any required libraries is all the documentation I need.
