geojson to json --missing multiple row output

[snippsat]

I apologize but having ssl cert issue and it is not letting me

I guess that you have this on all pip install?
Try:

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org pip setuptools

Also GeoJSON is a specify format that many Python packages deal with,have you looked at this?
A quick search.
GeoPandas | PyGeoj | geojson

import geopandas as gpd

earth= gpd.read_file('zz.geojson')
print(earth.head())
