Domande frequenti

Quick answers.

How does it handle nested JSON objects?

The converter recursively traverses the JSON to create nested Go types. It produces either inline structs or separate named types depending on the complexity of the input.

What happens with null or empty values?

Fields with null values are typically mapped to `interface{}` or pointer types to handle optionality. You should verify these against your specific API requirements to ensure type safety.

Are the struct tags configurable?

The tool generates standard `json:` tags based on the original keys. It automatically sanitises keys that contain hyphens or spaces to ensure they are valid Go identifiers.

Is my JSON payload secure?

Yes. The conversion logic is executed entirely via JavaScript in your browser. No data is transmitted to an external server during the generation process.
