What is Object Architect?
Object Architect is an AI-powered schema generator that creates TypeScript interfaces, JSON schemas, and mock data from various inputs. You can provide sample JSON and get perfectly typed interfaces, or describe your data structure in plain English and let AI generate the complete schema. It's the fastest way to go from data to types in TypeScript projects.
Why Use This Tool?
Manually writing TypeScript types for API responses is tedious and error-prone. You need to analyze JSON structure, identify optional fields, detect array types, and handle nested objects. Object Architect automates this entirely - paste JSON and get accurate TypeScript interfaces in seconds. The AI even detects patterns like ISO dates, UUIDs, and email addresses to use appropriate types instead of just "string".
How to Use Object Architect
- Paste sample JSON or describe your data structure in English
- Select output format: TypeScript, JSON Schema, Zod, or Yup
- AI analyzes the structure and generates the schema
- Review and customize generated types
- Copy or download the generated code
- Optionally generate matching mock data
Features
- JSON to TypeScript interface generation
- Natural language to TypeScript ("a user with name, email, orders")
- Pattern detection: dates, UUIDs, emails, URLs, phone numbers
- Nested object support with separate interface generation
- Array type inference from sample data
- Optional property detection
- JSON Schema (draft-07) generation
- Zod and Yup schema generation for runtime validation
Common Use Cases
- API Integration: Generate types from API response samples
- Backend Development: Create schemas for database models
- Form Validation: Generate Zod schemas for form validation
- Documentation: Create JSON schemas for API documentation
- Type Safety: Convert JavaScript objects to typed interfaces
Tips & Best Practices
- ✓ Provide multiple JSON samples for better optional property detection
- ✓ Use descriptive property names for better AI inference
- ✓ Generated Zod schemas can validate runtime data, not just compile-time
- ✓ Export interfaces to separate files for better code organization
How It Compares to Alternatives
json2ts and similar tools do basic JSON to TypeScript conversion. Object Architect uses AI to infer better types (ISO dates vs strings), detect patterns, and even generate schemas from natural language descriptions. Unlike QuickType, it runs entirely in your browser.
Frequently Asked Questions
Can I convert JSON into TypeScript interfaces or Java POJOs?
Yes. Paste your JSON or XML schema and Object Architect generates TypeScript interfaces, Java POJOs, or Go structs with clean field naming and type inference.
Does the object generator handle nested schemas?
It supports nested objects, arrays, and optional fields, producing strongly typed models that mirror your API payloads.
