Is there an Audit Log reader for Archived SPP Audit Logs that have been archived?

When the SPP Audit logs are archived, Audit Logs are stored in the Archive server and removed from the Appliance.

Do we have an app/reader that can process the Archived SPP Audit logs? the archived audit logs are in JSON format and it's a lot of columns etc and information are stored in many files. Searching and sorting can become cumbersome, even impractical.

It would be nice if there was a Reader that would provide the same functionality as the SPP Activity Center, providing the same functionality.
