[Answered ]-What JSON parser does Django Fixture Loading Use

Django fixtures are loaded using loaddata management command which uses built-in django deserializers which use json module from the standard library.

Fixtures are slow and difficult to maintain. Consider using model factories instead. Basically, there are two major players out there:

• factory_boy
• model_mommy
