You can use this tool to validate COUNTER Release 5 JSON or Tabular reports.
We encourage all content providers to test their reports each month.
The Validation Tool detects if metrics are missing or if the counts don’t make sense. For example, the Validation Tool will detect when there are less Total_Item_Requests than Unique_Item_Requests for a title (which would be a critical error). Please note that it is only possible to fully check if Unique_Title metrics are missing when the Data_Type is known, i.e. only for Master Reports with Data_Type included, TR_B1 and TR_B3.
