Mule Data Integrator 
Mule Data Integrator is a data transformation tool that allows you to easily transform your data from one format to another. Because it uses a graphical user interface, you can quickly map input fields to output fields by dragging and dropping, and the visual display of your map makes it easy to see exactly how your data transformation will behave before you run it.
Mule Data Integrator is free to try out and use in development, so you can do a full proof of concept and test your transformations with Mule instances running in the Mule IDE. When you are ready to go into production, you purchase a subscription from MuleSoft that enables you to run the data transformations on Mule instances that are running outside of the Mule IDE (Mule instances running standalone or embedded in a container).
