When the scan finishes, Grackle Sheets arranges the document’s elements and structures into 4 categories.
These categories can be seen in the user interface on the right side of the screen.
Elements in each are marked as either accessible or inaccessible. Changes are made by selecting and editing these elements in these categories. For example, a table does not have the header row specified with a tag.
