JSON to Django Model

About This Tool

Drafts a Django models.Model class from a JSON sample: strings become CharField, whole numbers IntegerField, decimals FloatField, booleans BooleanField, and nested objects/arrays JSONField: each with a TODO comment where a human decision (max length, choices, a real relation) is still needed. The swap button also runs backwards, turning an existing model class into realistic sample JSON by reading field names and types.

This is a starting draft, not a migration-ready schema, see the warning banner above. For a non-Django Python type instead, use JSON to Python.

Key Features

• Type-to-field inference: maps JSON value types to the closest Django field class, each flagged with a review comment.
• Reverse conversion: the ⇌ swap button turns a pasted Django model into sample JSON, picking realistic values (email, URL, UUID, FK id, M2M list) from the field name and type.
• Null handling: a field observed as JSON null gets null=True, blank=True plus a comment to confirm the real type.
• Configurable model name: the Model name field is PascalCased automatically into the class name.
• Persistent draft warning: a banner above the editors stays visible as a reminder to review before makemigrations.

Example

{"title": "Post", "views": 12, "published": true}

produces:

class Model(models.Model):
    title = models.CharField(max_length=255)  # TODO: confirm max_length
    views = models.IntegerField()
    published = models.BooleanField(default=False)
