Google Refine is a power tool for working with messy data, cleaning it up, transforming it from one format into another, extending it with web services, and linking it to databases like Freebase.
Google Refine is a desktop application that you download, install, and run on your own computer. However, unlike most other desktop applications, it runs as a small web server on your own computer.
