I've updated my MacMRU parser script, located here: https://github.com/mac4n6/macMRU-Parser.
This update includes support for 'Most Recently Used' artifacts for Microsoft Office for Mac 2011 and 2016. I've also added a bit more error checking, so please let me know if you come across a plist that doesn't work or does not contain certain expected keys. It happens, I've run across a few myself - I can't explain why now, but I hope to look into it further.
While researching for this update I noticed something interesting. Microsoft Office used a binary plist format for the 2011 version of the software, but "downgraded" to an XML-based plist format in the 2016 version. Most of the time I see plists headed in the XML->Binary direction.
Got a MacMRU file that I don't parse? Please let me know!
I hope you find this script useful!
