jsonpickle
jsonpickle is a library for the two-way conversion of complex Python objects and JSON. jsonpickle builds upon existing JSON encoders, such as simplejson, json, and ujson.
For complete documentation, please visit the jsonpickle documentation.
Bug reports and merge requests are encouraged at the jsonpickle repository on github.
Why jsonpickle?
Data serialized with python’s pickle (or cPickle or dill) is not easily readable outside of python. Using the json format, jsonpickle allows simple data types to be stored in a human-readable format, and more complex data types such as numpy arrays and pandas dataframes, to be machine-readable on any platform that supports json. E.g., unlike pickled data, jsonpickled data stored in an Amazon S3 bucket is indexible by Amazon’s Athena.
Security
jsonpickle should be treated the same as the Python stdlib pickle module from a security perspective.
Install
Install from pip for the latest stable release:
pip install jsonpickle
Install from github for the latest changes:
pip install git+https://github.com/jsonpickle/jsonpickle.git
Numpy/Pandas Support
jsonpickle includes built-in numpy and pandas extensions. If you would like to encode sklearn models, numpy arrays, pandas DataFrames, and other numpy/pandas-based data, then you must enable the numpy and/or pandas extensions by registering their handlers:
>>> import jsonpickle.ext.numpy as jsonpickle_numpy >>> import jsonpickle.ext.pandas as jsonpickle_pandas >>> jsonpickle_numpy.register_handlers() >>> jsonpickle_pandas.register_handlers()
Development
Use make to run the unit tests:
make test
pytest is used to run unit tests internally.
A tox target is provided to run tests using all installed and supported Python versions:
make tox
jsonpickle itself has no dependencies beyond the Python stdlib. tox is required for testing when using the tox test runner only.
The testing requirements are specified in setup.cfg. It is recommended to create a virtualenv and run tests from within the virtualenv.:
python3 -mvenv env3 source env3/bin/activate pip install --editable '.[dev]' make test
You can also use a tool such as vx to activate the virtualenv without polluting your shell environment:
python3 -mvenv env3 vx env3 pip install --editable '.[dev]' vx env3 make test
If you can’t use a venv, you can install the testing packages as follows:
pip install .[testing]
jsonpickle supports multiple Python versions, so using a combination of multiple virtualenvs and tox is useful in order to catch compatibility issues when developing.
GPG Signing
Unfortunately, while versions of jsonpickle before 3.0.1 should still be signed, GPG signing support was removed from PyPi (https://blog.pypi.org/posts/2023-05-23-removing-pgp/) back in May 2023.
