You can use json.dumps like so:

@app.route('/')
def home():
return render_template(
    'index.html',
    title='Home Page',
    result=json.dumps({"a":[{"o":1},{"o":2}]}, sort_keys = False, indent = 2)
)

and just format it in the template like so:

{% if result %}
   <pre>{{ result }}</pre>
{% endif %}

If this fits to your expectations. I think that jsonify is used to provide http.response data, not context data for templates.
