The yojson library

The Yojson library provides runtime functions for reading and writing JSON data from OCaml. The design goals of Yojson are the following:

  • Allowing type-aware serializers/deserializers to read and write directly without going through a generic JSON tree, for efficiency purposes.
  • Distinguishing between ints and floats.
  • Providing optional extensions of the JSON syntax. These extensions include comments, arbitrary strings, optional quotes around field names, tuples and variants.

See JSON specification.
