is there any way do the urldecode in Django template file?

Just opposite to urlencode or escape

I want to convert app%20llc to app llc

you have to write something like this instead of the previous answer otherwise you will get a maximum recursion depth

from urllib import unquote
from django.template.defaultfilters import register
from urllib.parse import unquote #python3@register.filter
def unquote_new(value):return unquote(value)

{{ raw|unquote_new }}
