Following up on the introductory video to Google Refine, this video focuses on data transformations. It shows how Google Refine can be used to transform a dataset from one format to another. This includes the use of facets and filters to isolate subsets of the data and act upon them to clean up the data. It also includes exporting the data in various formats (such as JSON). A history of transformation operations can be saved and reused on future datasets.
