Cleaning & transforming your data with Stanford’s Wrangler

Wrangler Demo Video from Stanford Visualization Group on Vimeo.

“Too much time is spent manipulating data just to get analysis and visualization tools to read it. Wrangler is designed to accelerate this process: spend less time fighting with your data and more time learning from it. Wrangler allows interactive transformation of messy, real-world data into the data tables analysis tools expect. Export data for use in Excel, R, Tableau, Protovis, …”

Seeing how this is from Stanford University, there’s a nice paper as well, “Wrangler: Interactive Visual Specification of Data Transformation Scripts”. There’s a bit of an overlap between FreeBase’s Gridworks (now Google’s Refine tool) but really, more differences than similarity. But they both work in your browser–try Wrangler right now.
