OpenRefine
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.
- OpenRefine is a popular tool for Wikidata batch editing since 2018.
- OpenRefine supports Wikimedia Commons batch editing and uploading, thanks to a Wikimedia grant, since 2022.
- OpenRefine can also be used to batch import and edit data items and media files in Wikibases.
OpenRefine is a community-supported open source project, licensed under the BSD license. It has a graphical user interface in more than 15 languages.
