How to Generate Clean TypeScript Interfaces from JSON

Converting massive, nested JSON payloads into TypeScript interfaces manually is error-prone and tedious. Our tool automates this process while ensuring high-quality, readable code.

🛠️ Key Features for Developers

  1. Nested Object Resolution: Automatically flattens and creates separate interfaces for deeply nested objects.
  2. Type Inference: Decides whether a field should be a string, number, boolean, or even a union type if samples vary.
  3. PascalCase Conversion: Automatically renames your interfaces to match standard TypeScript naming conventions.

🚀 Workflow Integration

  • Copy from Network Tab: Simply right-click a network response in Chrome DevTools, 'Copy Response', and paste it here.
  • Rename as You Go: You can instantly rename the root interface to match your domain model.

Frequently Asked Questions

Q. Does it handle arrays correctly?

Yes. If an array contains objects, it will create a distinct interface for that object type and reference it as `TypeName[]`.

Q. Is there a limit on JSON size?

The tool can comfortably handle JSON files up to 5MB entirely in your browser.

Q. Can I export to a .ts file?

Currently, we provide a 'One-Click Copy' feature, which is the fastest way to move code into your IDE.
