bonobo

"Bonobo is a line-by-line data-processing toolkit for python 3.5+ emphasizing simple and atomic data transformations defined using a directed graph of plain old python callables (functions and generators).

Bonobo is a extract-transform-load framework that uses python code to define transformations.

You can either use the built in extractors for standard file formats (CSV, JSON, XML, XLS, ...), use official add-ons to connect to usual external services (SQL), or write your own extractors.

Wrangling data is great, but keeping it around is better. Use our standard writers (CSV, JSON, XML, XLS, ...) or connect to your custom services."
