I just started messing around with some machine learning algorithms, and discovered most of my time is spent cleaning up data. What tools are available for seeing anomalies in data and cleaning it up?<p>I know there&#x27;s OpenRefine (open source, but abandoned) and DataWrangler (research project, also abandoned as originators went to create a company) for non-technical people. And for programmers, it&#x27;s usually some version of SQL or using Python&#x27;s Panda or R.<p>Something like OpenRefine looks great, but doesn&#x27;t operate on databases. I&#x27;m willing to pay for something, but not the usual enterprise software prices. Looking for something like...an Excel for data cleaning. Anyone know of something that might fit the bill?
