Read saved player data in addition to logs

[fidian]

I hosted a server on the Relams for quite some time before hosting it myself. I do not have access to those logs. Things like achievements and the amount of time played does not accurately reflect the users on my server.

Would it be possible to scan the player stats folder (stats/*.json) for statistics so I can have them be more accurate?

Edit: Changed from NBT playerdata to the JSON stats instead.
