Low-level JSON parsing and pretty-printing library for OCaml
Yojson is a low-level JSON parsing and pretty-printing library for OCaml that parses JSON and JSON5 data into nested OCaml tree data structures. Built in OCaml, the library provides both standard Yojson and an alternative Yojson-five variant, and serves as the foundation for several related tools in the OCaml ecosystem. The project is developed and maintained by volunteers in the OCaml community and is licensed under the 3-clause BSD license.
