OpenRefine (formerly Google Refine) is a free, open source tool for working with messy data: cleaning it; transforming it from one format into another; and extending it with web services and external data. In this workshop, we’ll go through how to use OpenRefine to explore your data, clean it, transform it, and prep it for further analysis or visualization work. This is an introductory session; no prior experience with OpenRefine is required. A basic understanding of tabular data (spreadsheets) and familiarity with Microsoft Excel is helpful.
