.. py:function:: to_json(model: cobra.Model, sort: bool = False, **kwargs: Any) -> str

   Return the model as a JSON string.

   :param model: The cobra model to represent.
   :type model: cobra.Model
   :param sort: Whether to sort the metabolites, reactions, and genes or maintain the
                order defined in the model (default False).
   :type sort: bool, optional
   :param \*\*kwargs: Keyword arguments passed on to `json.dumps`.
   :type \*\*kwargs: Any

   :returns: JSON string representation of the cobra model.
   :rtype: str

   .. seealso::

      :obj:`save_json_model`
          Write directly to a file.

      :obj:`json.dumps`
          Base function.


.. py:function:: from_json(document: str) -> cobra.Model

   Load a cobra model from a JSON string.

   :param document: The JSON string representation of a cobra model.
   :type document: str

   :returns: The cobra model as interpreted from the JSON string.
   :rtype: cobra.Model

   .. seealso::

      :obj:`load_json_model`
          Load directly from a file.


.. py:function:: save_json_model(model: cobra.Model, filename: Union[str, pathlib.Path, IO], sort: bool = False, pretty: bool = False, **kwargs: Any) -> None

   Write the cobra model to a file in JSON format.

   :param model: The cobra model to represent.
   :type model: cobra.Model
   :param filename: File path or descriptor that the JSON representation should be
                    written to.
   :type filename: str or file-like
   :param sort: Whether to sort the metabolites, reactions, and genes or maintain the
                order defined in the model (default False).
   :type sort: bool, optional
   :param pretty: Whether to format the JSON more compactly (default) or in a more
                  verbose but easier to read fashion. Can be partially overwritten by the
                  `**kwargs` (default False).
   :type pretty: bool, optional
   :param \*\*kwargs: Keyword arguments passed to `json.dump`.
   :type \*\*kwargs: Any

   .. seealso::

      :obj:`to_json`
          Return a string representation.

      :obj:`json.dump`
