ETLPlus

One engineer's personal project, written outside client work. ETLPlus moves data between REST APIs and files in dozens of formats, from CSV and JSON to Parquet, Avro and DuckDB, and checks it on the way with type, range, pattern and required-field rules.

Pipelines can be checked for order and readiness before they run, table specs render to SQL, and a local dashboard shows run history.
