A diff/patch pair for JSON-serialized data structures.

Project description

This is a forked version of json-delta which uses ujson instead of the standard library json package. This should speed things up a bit. Also includes changes to make more PEP-8 compliant. This is built for Python 3+ since you should be using that now;)

From the original version: json-delta v1.1.3: A diff/patch pair and library for JSON data structures. (

JSON-delta is a multi-language software suite for computing deltas between JSON-serialized data structures, and applying those deltas as patches. It enables separate programs at either end of a communications channel (e.g. client and server over HTTP, or two processes talking to one another using bidirectional IPC) to manipulate a data structure while minimizing communications overhead.

This is the python implementation. It requires Python version 2.7 or newer (including Python 3). It can be installed in the standard way:

$ python install

(potentially needing superuser privileges). This will install a single module named json_delta, and scripts named json_diff, json_patch and json_cat.

HTML documentation for all four of these can be found in the doc/ directory, along with manpages for the scripts.

Donations to support the continuing development of JSON-delta will be gratefully received via gratipay (, PayPal ( or Bitcoin: (1HPJHRpVSm1Y4zrgppd2c6LysjxeabbQN4).
