B. Transformer Toolbar

The Transformer Toolbar contains different Transform options and tools available within Trifacta.

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 creating the transformation using the Transform Builder.

The toolbar also contains the options to switch between Grid view and Columns View of your data.

To learn more about Transformer toolbar icons individually, read this detailed documentation guide.

C. Data Grid

The grid is the default view in the Transformer page of Trifacta Wrangler.

The Data Grid displays the sample of the data from the dataset and will dynamically update when you add transformations. The data is presented in rows and columns , with the column name and inferred data type at the top of each column. For each column, there is also a Data Quality Bar and Histogram, which shows a profile of the values.

Click column headings to review a visual profile of the column's data and a set of suggestions for transformations to apply to the column.
