Django fixtures allow the loading of initial data into Django models in formats such as JSON, XML, and YAML. To use fixtures, create a folder for fixtures, prepare a data file with a specified structure, and utilize the command 'python manage.py loaddata fixture_file.json' to insert the data into the database. The document provides examples and syntax for creating and loading fixture data into Django applications.
