In the Data panel, there's raw data, and most of it has no formatting whatsoever. This cannot be easily interpreted by business users. Due to this, before creating the charts to visualize our data, we would need to clean it up so as to make it presentable and understandable. Cleaning the data can be done in the Grid or Facets view. To the right of the Data panel, we have the data editing panel, which allows us to perform column management tasks, such as column duplication, splitting, renaming, and removing. Similarly, row-level editing tasks such as setting values to lowercase, finding and replacing, adding or trimming text, and adding formulas can be performed. Editing tasks can be applied to selected columns or to all of them.
