class jsonpickle(obj, filename=None, tostring=False, **kwargs)[source]#

Save any Python object to a JSON using jsonpickle.

Wrapper for the jsonpickle library: https://jsonpickle.github.io/

Note: unlike regular pickle, this is not guaranteed to exactly restore the original object. For example, at the time of writing it does not support pandas dataframes with mixed-dtype columns. If this sort of thing does not sound like it would be an issue for you, please proceed!

  • obj (any) – the object to pickle as a JSON

  • = (filename) –

  • tostring (bool) – whether to return a string (rather than the JSONified Python object)

  • kwargs (dict) – passed to jsonpickle.pickler.Pickler()


Either a Python object for the JSON, a string, or save to file


# Create data
df1  = sc.dataframe(a=[1,2,3], b=['a','b','c'])

# Convert to JSON and read back
json = sc.jsonpickle(df1)
df2  = sc.jsonunpickle(json)

# Save to JSON and load back
sc.jsonpickle(df1, 'my-data.json')
df3  = sc.jsonunpickle('my-data.json')

New in version 3.1.0: “filename” argument
