Just save it to a file and use ausearch -i to do the interpolation for
you.  For example:

ausearch -if /tmp/testentry -i

where /tmp/testentry contains the below entry

Run it on the same system it was generated on so the UID and other lookups
are accurate

The ausearch program is able to decode this and is meant to display the audit 
loags. If you have that in a file named log, you can just do something like 

ausearch -if log -i

and that should decode your event.
