One approach would be to first make an untitled notebook, then update the model:

Solved here: https://github.com/ipython-contrib/IPython-notebook-extensions/issues/282. The ~/.jupyter/nbconfig/notebook.json file must be edited to use python-markdown/main instead of python-markdown.

More generally this kind of error can also happen after you've upgraded Jupyter/Python/etc and some of the extensions are not supported by your updates. You can then just disable them from the Nbextensions configuration tab - you may find that they're the extensions that are shown as incompatible - which can be disabled by ticking the 'disable configuration for nbextensions without explicit compatibility' checkbox.

If you want to load a json file use pandas.read_json.
pandas.read_json("pud.json")
This will load the json as a dataframe. The function usage is as shown below
pandas.read_json(path_or_buf=None, orient=None, typ='frame', dtype=True, convert_axes=True, convert_dates=True, keep_default_dates=True, numpy=False, precise_float=False, date_unit=None, encoding=None, lines=False, chunksize=None, compression='infer')
You can get more information about the parameters here http://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_json.html

Another way using json!
import pandas as pd
import json
with open('File_location.json') as f:
data = json.load(f)
df=pd.DataFrame(data)

How to load extension automatically after a new notebook tab created? · Issue #365 · jupyter/notebook
August 30, 2015 - In IPython Notebook 2.X I can pass --ext parameter to ipython notebook command line to automatically load an extension so that I can do some initialization work. Just like ipython notebook --ext=mymodule.extention. But when I upgrade to new jupyter 4.X, this way is not work any more, it'll say Unrecognized alias: '--ext=mymodule.extension', it will probably have no effect.

The nice rendering is enabled by npmjs.com/package/@jupyterlab/json-extension. GitHub uses (possibly an outdated version of) nbviewer to render notebooks. Does it work in nbviewer? If yes, then you should probably request this as a feature from GitHub.
