In this chapter, you have got to know OpenRefine, your new best friend for data profiling, cleaning, transformation, and many other things that you are still to discover. You now have an OpenRefine installation running and you know how to import your data into it by creating a new project and how to export them again after you are done. The mechanisms of rows and columns do not have any secrets for you any longer, and you understand how to navigate in the project history. You have also mastered memory allocation, which allows you to work on larger datasets.
Although it is always important to first have a good overview of what is in your dataset before dirtying your hands, you may now be getting impatient to perform actual changes on your data. If so, you are ready for Chapter 2, Analyzing and Fixing Data, which will move on to teach you the ins and outs of all the basic operations needed to analyze and fix your data.
