Invisible player due value in playerdata file, how to fix that without headache?

Hi, I have some weird case. By some reason (probably crash of the server and consequences) some players began to be invisible. During some research I found that problem is with value in player's NBT data. Entry called Bukkit.invisible for some of them is set for 1, but after change to 0, everything is fine. My question is, is it possible to change that value for specific players automatically, or at least without manually editing value for each player (it can be hundreds of files...) via NBTExplorer? Server is using PaperMC, of course set in online mode.

yeah, thanks for information about dynmap. The good news is I've installed that plugin couple of hours ago so not yet shared (and obviously not finished rendering)

About the main question it looks like the easiest way will be just made a script in Python that just iterates for each playerdata and fixes value when is invalid. I will share it when will be done and can confirm it works Well. I've fixed it. I was forced to iterate per each playerdata file and if is necessary remove Bukkit.invisible tag, and then just replace files. Of course everything on turned off server. If someone interested, here's the script: 
#!/usr/bin/env python3
