DataCleaner

The premier Open Source Data Quality solution.

DataCleaner is a Data Quality toolkit that allows you to profile, correct and enrich your data. People use it for ad-hoc analysis, recurring cleansing as well as a swiss-army knife in matching and Master Data Management solutions.

Project status

The project is maintained, but is not being actively developed:

• We ensure that DataCleaner runs on modern versions of Java on major operating systems.
• We take security bugs serious and try to keep dependencies up to date whenever there are vulnerabilities detected.
• We are open for bug reports, contributions and discussions.
• New features are driven by pull requests.

The current maintainer of the project is @kaspersorensen.
