 ## Typical workflow
 
 **Step 1**: Do some experiments with your data (or parts of it) in the graphical user interface of OpenRefine. If you are fine with all transformation rules, [extract the json code](http://kb.refinepro.com/2012/06/google-refine-json-and-my-notepad-or.html) and save it as file (e.g. dedup.json).
