For reducing the number of table I put the values of table as json string and stored it in a text field my problem I override the admin view of the specific model with now I have to render the the text field with json data in well defined tabular format

This is the value of the json string I have to render in the change_form.html that I already overrided [{'name': 'name', 'value': 'dfgdgd', 'label': 'Name used Account', 'type': 'text'}, {'name': 'email', 'value': '[email protected]', 'label': 'Account Email Address', 'type': 'text'}, {'name': 'url', 'value': 'sdfsdfsdf', 'label': 'Web Address (URL)' , 'type': 'text'}]

Use json.loads to convert the json string into dict, then pass it to template. – Qiang Jin
What you have posted is not valid json. – Burhan Khalid

You need to convert the json back into an object, and pass that object to the template:

import json

def my_view(request):
    s = "[{'name': 'name', 'value': 'dfgdgd', 'label': 'Name used Account', 'type': 'text'}, {'name': 'email', 'value': '[email protected]', 'label': 'Account Email Address', 'type': 'text'}, {'name': 'url', 'value': 'sdfsdfsdf', 'label': 'Web Address (URL)' , 'type': 'text'}]"
    s = s.replace("'",'"') # json must be double quoted
    o = json.loads(s)
    return render(request, 'template.html', {'data': o})

Then in your template:

{% for obj in data %}
    {{ obj.name }} - {{ obj.value }} - {{ obj.label }} - {{ obj.type }}
{% endfor %}
