Serialization¶

To Dict¶

In order to convert the DeepDiff object into a normal Python dictionary, use the to_dict() method.

Example:

>>> t1 = {1: 1, 2: 2, 3: 3, 4: {"a": "hello", "b": [1, 2, 3]}}
>>> t2 = {1: 1, 2: 2, 3: 3, 4: {"a": "hello", "b": "world\n\n\nEnd"}}
>>> ddiff = DeepDiff(t1, t2)
>>> ddiff.to_dict()
{'type_changes': {"root[4]['b']": {'old_type': <class 'list'>, 'new_type': <class 'str'>, 'old_value': [1, 2, 3], 'new_value': 'world\n\n\nEnd'}}}

Note that you can override the View that was originally used to generate the diff here.

Example:

>>> t1 = {1: 1, 2: 2, 3: 3, 4: {"a": "hello", "b": [1, 2, 3]}}
>>> t2 = {1: 1, 2: 2, 3: 3, 4: {"a": "hello", "b": "world\n\n\nEnd"}}
>>> ddiff = DeepDiff(t1, t2, view='tree')
>>> ddiff.to_dict(view_override='text')
{'type_changes': {"root[4]['b']": {'old_type': <class 'list'>, 'new_type': <class 'str'>, 'old_value': [1, 2, 3], 'new_value': 'world\n\n\nEnd'}}}

To Json¶

In order to do safe json serialization, use the to_json() method.

Example:

>>> t1 = {1: 1, 2: 2, 3: 3, 4: {"a": "hello", "b": [1, 2, 3]}}
>>> t2 = {1: 1, 2: 2, 3: 3, 4: {"a": "hello", "b": "world\n\n\nEnd"}}
>>> ddiff = DeepDiff(t1, t2, view='tree')
>>> ddiff.to_json()
'{"type_changes": {"root[4][\'b\']": {"old_type": "list", "new_type": "str", "old_value": [1, 2, 3], "new_value": "world\\n\\n\\nEnd"}}}'

To Json Pickle¶

If you want the original DeepDiff object to be serialized with all the bells and whistles, you can use the to_json_pickle() and from_json_pickle() in order to serialize and deserialize its results into json. Note that json_pickle is unsafe and json pickle dumps from untrusted sources should never be loaded. It is recommended not to use this serialization unless you have to.

Note

You need to install the jsonpickle package to use the to_json_pickle() method.

Serialize and then deserialize back to deepdiff

>>> t1 = {1: 1, 2: 2, 3: 3}
>>> t2 = {1: 1, 2: "2", 3: 3}
>>> ddiff = DeepDiff(t1, t2)
>>> jsoned = ddiff.to_json_pickle()
>>> jsoned
'{"type_changes": {"root[2]": {"new_type": {"py/type": "builtins.str"}, "new_value": "2", "old_type": {"py/type": "builtins.int"}, "old_value": 2}}}'
>>> ddiff_new = DeepDiff.from_json_pickle(jsoned)
>>> ddiff == ddiff_new
True

From Json Pickle¶

Load the diff object from the json pickle dump. Take a look at the above To Json Pickle for an example.
