This tool converts JSON objects into Mongoose schemas. It automatically maps JSON types (string, number, boolean, object, array) to Mongoose SchemaTypes (String, Number, Boolean, Schema.Types.Mixed, Array). It also handles nested objects by creating sub-schemas or nested paths, providing a solid starting point for your MongoDB data modeling.

Paste your JSON data into the input field. The tool will analyze the structure and generate a Mongoose Schema definition, including field types, nested objects, and arrays. You can then copy this schema to use in your MongoDB-based Node.js applications.

Manually defining Mongoose schemas for complex JSON data can be tedious and prone to errors. This converter automates the process, ensuring that your schema accurately reflects your data structure. It saves time during development and helps maintain consistency between your data and your database models.

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 userSchema = new mongoose.Schema({
  id: Number,
  name: String,
  email: String,
  isActive: Boolean,
  tags: [String],
  profile: {
    bio: String,
    skills: [String]
  }
});

Invalid JSON

Fix: Check your JSON syntax for missing commas or quotes.

Ambiguous Types

Fix: If a field is null or an empty array, the tool might default to Mixed or [Mixed]. Manually specify the type if known.

Does it support nested schemas?

Yes, it handles nested objects and arrays of objects by creating nested paths.

Can I add validation rules?

The tool generates the basic structure; you can manually add "required", "unique", or "default" properties to the generated schema.
