# Data Controller for SAS: User Guide ## Overview The Data Controller has 5 tabs, as follows: * Viewer. This tab lets users view any table to which they have been granted access in metadata. They can also download the data as csv, excel, or as a SAS program (datalines). * Editor. This tab enables users to add, modify or delete data. This can be done directly in the browser, or by uploading a CSV file. Values can also be copy-pasted from a spreadsheet.
