OpenRefine is a free data wrangling tool that can be used to process, manipulate and clean tabular (spreadsheet) data and connect it with knowledge bases ("spreadsheets on steroids" / "a swiss army knife for data"). It is widely used by librarians, in the cultural sector, by journalists and scientists, and is taught in many curricula and workshops around the world. The Wikimedia movement and individual Wikimedians actively participate in OpenRefine's community. This page lists distinct projects and initiatives.
