Example report viewer
This page displays a saved result from running the supplied sample. It does not execute Python or process your files. Download the starter and follow the guide to run it locally with Python 3.11+.
Run the actual project
python -m unittest discover -s tests -v python -m etl --source examples/orders.csv --database data/orders.sqlite3 --output output
The fictional sample has two valid orders and two intentionally invalid records. Exit code 2 flags quarantine; a repeat run leaves existing orders unchanged.
Includes source, sample data, tests, a guide, Docker and CI templates. Adapt the schema and add your own deployment, monitoring and backup controls before production use.
