convert %player% to player's uuid

[ECSE]

sorry for my poor english.

i used whole variables as %player%.
but when player's nickname changed, data was disappeared.
so i convert this variables player -> player's uuid.
how to convert them?
just change in config in skript folder?

config in skript folder:
use player UUIDs in variable names: false -> true

Let's hope you used list variables, you can convert them using

loop {oldvariable::*}:
    set {newvariable::%loop-index%} to loop-value

And changing the value in the config folder only works for new variables, old ones won't get converted
