JSON → POJO Converter
Generate Java POJO drafts from JSON text, a local file or a URL when the browser permits the request. Configure the package, class naming, Java version, arrays, dates, null handling and optional Jackson, Gson, Lombok or validation annotations. The generator infers types from the sample, merges array samples and falls back to Object for incompatible values; review and compile the output because JSON binding is not verified.
Features
- Accept JSON text, local files or a URL when browser CORS allows it.
- Configure package, root class, naming convention and Java/build settings.
- Control arrays, dates, numbers, nulls and optional framework annotations.
- Review generated classes and download one file or the complete set.
How to use
- Paste JSON, upload a file or enter a URL that permits browser access.
- Choose package, class, naming and annotation options.
- Generate the POJOs and inspect inferred fields, arrays and types.
- Download the generated classes and compile or test them in your project.
