Часто задаваемые вопросы

Quick answers.

How does the tool handle nested objects?

The converter recursively traverses the JSON structure and creates separate, named interfaces for nested objects to ensure the code remains modular and readable.

What happens with null values or empty arrays?

When a value is `null`, the tool typically types it as `any` or `unknown` because the intended type cannot be inferred. For empty arrays, it defaults to `any[]` unless further context is provided.

Can I customise the root interface name?

Yes. You can specify a custom name for the top-level interface to match your project's naming conventions, and the tool will update all references accordingly.

Is my data privacy protected?

Yes. The parsing and interface generation logic runs locally in your browser session. No data is sent to our servers or stored externally.
