you don't need the \usemodule any more.

Thank you!
I need to run it on a server with TeXlive 2023, and there the module
is still needed. But it works, and the code is much simpler than before.
Here is your monthly undocumented feature:
Thank you! Sorry, I overlooked your answer.
\usemodule[json]
\starttext
\startluacode
local t = {
a = {
b = {
c = "here",
}
},
b = "there",
d = { 1, 2, 3, 4 },
}
utilities.tablestore.load("crap",t)
io.savedata("oeps.json",utilities.json.tojson(t))
\stopluacode
\tablefield {crap}{a.b.c}
\tablefield {crap}{b}
\tablelength{crap}{d}
\loadtable[whatever][oeps.json]
\tablefield {whatever}{a.b.c}
\tablefield {whatever}{b}
\tablelength{whatever}{d}

I could probably extend this a bit (and then optimize it performance
wise) but I have zero application for it; typical stuff that evolves in
a project.
At the moment, I only need to read in the structure and handle it in Lua
(CLD), no need for extensions.
But I’ll happily document this.
