An optimized parsing and printing library for the JSON format
Yojson is an optimized parsing and printing library for the JSON format. It addresses a few shortcomings of json-wheel including 2x speedup, polymorphic variants and optional syntax for tuples and variants. ydump is a pretty-printing command-line program provided with the yojson package. The program atdgen can be used to derive OCaml-JSON serializers and deserializers from type definitions.
