XML to TypeScript Interface Converter

How to use

1. Paste XML input from your API payload or sample document.
2. Select your output target and model options.
3. Generate, review, and copy the result.

Benefits

• Handles nested elements, repeated nodes, and attribute groups from XML documents.
• Reduces manual model writing and naming inconsistencies.
• Works instantly in browser with copy-ready output.

Best use cases

• Generate frontend API response contracts for React and Next.js features.
• Share interface definitions across service layers and UI components.
• Catch payload drift early with strict TypeScript checks.

Type mapping notes

• JSON numbers map to TypeScript number fields.
• Nested JSON objects become reusable child interfaces.
• Array item types are inferred from sample payload elements.

Implementation tips

• Use stable root model names so imports remain predictable.
• Enable optional generation when payload fields are conditionally present.
• Store generated interfaces next to API client modules.

Sample XML

<user>
  <id>101</id>
  <name>Ada Lovelace</name>
  <active>true</active>
  <roles>
    <role>admin</role>
    <role>editor</role>
  </roles>
  <profile>
    <email>ada@example.com</email>
    <score>9.8</score>
  </profile>
</user>

Sample output

export interface UserModel {
  id: number;
  name: string;
  active: boolean;
  roles: string[];
  profile: Profile;
}

export interface Profile {
  email: string;
  score: number;
}
