jdiff is a lightweight Python library allowing you to examine structured data. jdiff provides an interface to intelligently compare JSON data objects and test for the presence (or absence) of keys. You can also examine and compare corresponding key-values.

The library heavily relies on JMESPath for traversing the JSON object and finding the values to be evaluated. More on that here.

Install from PyPI:

pip install jdiff

jdiff has been developed around diffing and testing structured data returned from APIs and other Python modules and libraries (such as TextFSM). Our primary use case is the examination of structured data returned from networking devices. However, we found the library fits other use cases where structured data needs to be operated on, and is especially useful when working or dealing with data returned from APIs.
