Pretty JSON Formatting in IPython Notebook

Solution 1:

json.dumps has an indent argument, printing the result should be enough:

print(json.dumps(obj, indent=2))

Solution 2:

This might be slightly different than what OP was asking for, but you can do use IPython.display.JSON to interactively view a JSON/dict object.

from IPython.display import JSON
JSON({'a': [1, 2, 3, 4,], 'b': {'inner1': 'helloworld', 'inner2': 'foobar'}})

Edit: This works in Hydrogen and JupyterLab, but not in Jupyter Notebook or in IPython terminal.

Inside Hydrogen:

Solution 3:

import uuid
from IPython.display import display_javascript, display_html, display
import json

class RenderJSON(object):
    def __init__(self, json_data):
        if isinstance(json_data, dict):
            self.json_str = json.dumps(json_data)
        else:
            self.json_str = json_data
        self.uuid = str(uuid.uuid4())

    def _ipython_display_(self):
        display_html('<div id="{}" style="height: 600px; width:100%;"></div>'.format(self.uuid), raw=True)
        display_javascript("""
        require(["https://rawgit.com/caldwell/renderjson/master/renderjson.js"], function() {
        document.getElementById('%s').appendChild(renderjson(%s))
        });
        """ % (self.uuid, self.json_str), raw=True)

To ouput your data in collapsible format:

RenderJSON(your_json)
