Quality Matrix
The Quality Matrix shows an overview of issues detected in your spreadsheet, shown by category, worksheet or (user-assignable) status.
Big numbers indicate how many kinds of issues were found for a given risk level.
Among Reference Issues, 1 inspection triggered risks, 1 triggered weaknesses and 3 triggered observations.
Small numbers indicate how many concrete cases were found in your spreadsheet.
Commonly different cases point to the same issue occurring in multiple places.
Taking Inventory
Click on any inspection result in the sidebar to reveal particular findings within your spreadsheet.
Issue Description
At the top you’ll find some general info (i.e. ‘Why might it worth to take a look at References to Empty Cells?’).
Individual Cases
