SmartAnalytics
SmartAnalytics has a lot of useful reports that you can run for your DFR catalog. There are general reports to review all your master attributes at once, who created them or changed them. There are analytical tools to look at fill rates on attributes or to analyze attribute values for a given category e.g. horsepower values for a motor's category. Lastly, you can also do a duplicate analysis and review the results in SmartFind. All reports can be exported to excel.
