This is one of the most accommodating pane since it facilitates most of the cleaning operations that you can perform on the data and it visually highlights the relationship between the fields. You can find out the number of unique values contained within each field and how they are distributed. The profile pane is the middle pane in the view and acts as a high-level overview of the data, illustrating each fields’ profile.
