Tablib: Pythonic Tabular Datasets by Kenneth Reitz and Bessie Monke.
From the post:
Tablib is an MIT Licensed format-agnostic tabular dataset library, written in Python. It allows you to import, export, and manipulate tabular data sets. Advanced features include, segregation, dynamic columns, tags & filtering, and seamless format import & export.
Definitely an add to your Python keychair USB drive.
I first saw this in a tweet by Gregory Piatetsky.
