No—do not install this package for new projects. It is deprecated and inactive; Django 3.1+ provides a native, maintained JSONField. If you maintain legacy code already using jsonfield, plan a migration to Django's implementation. The package carries no security vulnerabilities but receives no updates and will eventually be archived.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Django and Python 3.10 or later.
- Package is deprecated; Django 3.1+ users should migrate to models.JSONField instead.
- Low friction installation, but the package is marked inactive (Development Status 7) and explicitly deprecated since Django 3.1 introduced native JSONField support.

Verify before relying

What it is and what it does
jsonfield is a Django model field for storing JSON data that handles serialization and deserialization automatically. It wraps JSON values so they can be persisted to the database and queried using basic lookups (exact, regex). The field supports customization of null handling and deserialization behavior (e.g., using OrderedDict for key ordering).
However, this package is deprecated and no longer maintained. Django 3.1 introduced a native JSONField that works across all supported database backends, making jsonfield obsolete. The package's last release was over a year ago, and its status is marked inactive. New projects should use Django's built-in JSONField; existing projects using jsonfield should plan a migration, which the documentation describes as generally straightforward but may require data migrations in complex cases.
Use it for
- Storing flexible JSON structures in Django models when using older Django versions (pre-3.1) that lack native JSONField support.
- Migrating legacy Django applications that already use jsonfield and need to maintain compatibility during a transition period.
- Querying JSON fields with basic exact or regex lookups in projects that do not require advanced JSON query capabilities.
- Customizing JSON deserialization behavior (e.g., preserving key order with OrderedDict) in older Django codebases.
