OpenRefine is a free, open-source tool for working with messy data. OpenRefine intuitive interface for data discovery and preparation empowers those who understand the context in which the data are generated. The project started as Freebase Gridworks (released in 2010) and Google Refine until 2012. RefinePro is working with the OpenRefine community since 2011 when we started to publish tutorials.

At RefinePro, we use OpenRefine to profile data and prototype complex data projects. RefinePro also uses OpenRefine for nonrepeatable data cleaning projects, including one-time migration.

RefinePro helped several customers embed OpenRefine in their workflow with custom integrations, batch scheduling, and extensions development. We provided hosted or on-premise deployments enabling collaboration features and automation.
