Library documentation
Currently at https://ocaml-community.github.io/yojson/
Examples
A simple example on how to parse JSON from a string literal.
let json_string = {|
{"number" : 42,
"string" : "yes",
"list": ["for", "sure", 42]}|}
(* val json_string : string *)
let json = Yojson.Safe.from_string json_string
(* val json : Yojson.Safe.t *)
Format.printf "Parsed to %a" Yojson.Safe.pp json
Related tooling
Yojson is a pretty common choice for parsing JSON in OCaml, as such it is the base for a number of tools and libraries that are built on top of it.
