Easy Export

It parses JSON data and maps it to Sequelize DataTypes (STRING, INTEGER, BOOLEAN, JSON, etc.). It creates a model definition that you can directly paste into your Node.js application using Sequelize ORM.

Paste your JSON into the tool to generate a Sequelize model definition. It will produce the `sequelize.define` code block with appropriate DataTypes for each field.

Sequelize requires explicit model definitions. This tool saves you from manually typing out field names and types, especially for large JSON objects, ensuring your database model matches your data structure.

Example Input

{
  "id": 1,
  "name": "John Doe",
  "email": "john@example.com",
  "isActive": true,
  "tags": ["admin", "dev"],
  "profile": {
    "bio": "Software Engineer",
    "skills": ["Go", "React", "TypeScript"]
  }
}

Example Output

const User = sequelize.define("User", {
  id: { type: DataTypes.INTEGER, primaryKey: true },
  name: DataTypes.STRING,
  email: DataTypes.STRING,
  isActive: DataTypes.BOOLEAN,
  tags: DataTypes.JSON
});

Data Type Mismatch

Fix: Sequelize types might vary by database dialect. Review the generated types for your specific DB (e.g., MySQL vs PostgreSQL).

Does it handle associations?

It focuses on single model definitions. Associations should be defined separately using `belongsTo`, `hasMany`, etc.
