JSON to Prisma Schema: Auto-Generate Prisma Model Definitions

Accelerate Prisma Schema Development

Writing Prisma model definitions by hand for complex data structures is repetitive and error-prone. By pasting a sample JSON object, our generator produces a complete schema.prisma model block in seconds.

Type Mapping: JSON to Prisma

• string → String
• integer → Int
• float → Float
• boolean → Boolean
• ISO date string → DateTime
• null → optional field (String?)
• Nested object → separate model block with relation

Workflow: JSON API → Prisma → Database

1. Capture a sample API response JSON
2. Paste into the generator and set the model name
3. Copy the output into your schema.prisma file
4. Run prisma migrate dev to apply the schema

// JSON Input
{ "id": 1, "name": "Alice", "email": "a@example.com",
  "createdAt": "2024-01-01T00:00:00.000Z", "active": true }

// Generated Prisma Schema
model User {
  id          Int       @id @default(autoincrement())
  name        String
  email       String
  createdAt   DateTime
  active      Boolean
}
