よくある質問

Quick answers.

How does the tool determine data types?

It inspects the values in your JSON to map strings to `string`, numbers to `number`, and booleans to `boolean`. For complex objects or arrays, it generates relational skeletons or `jsonb` column types.

Are the generated decorators customisable?

The tool uses standard TypeORM defaults for decorators. You can manually adjust the generated `varchar` lengths or column names once the code is in your IDE.

Does this support nested objects?

Yes, nested objects are detected and can be represented as embedded entities or separate classes depending on your requirements. You may need to manually add `@OneToOne` or `@ManyToOne` decorators for complex relationships.

Is my JSON data secure?

The conversion logic is executed entirely via client-side JavaScript. Your JSON input and the resulting TypeScript output are never sent to a server.
