At the top of the data grid and the column browser, the Transformer toolbar provides quick access to common transformations. When a tool is selected from one of the drop-downs in the toolbar, a new step is inserted into the current location in your recipe with some parameters pre-specified for you. You can then finish specifying the parameters of the transformation in the Transform Builder.
Use these buttons to toggle between the data grid and column browser views of the Transformer page.
