No—install only if you are locked into an older Python environment and have no alternative. The package is abandoned with no maintenance since 2022, no releases since 2019, and no guarantee of compatibility with modern Python. For new projects, use maintained alternatives like dataclasses-json, pydantic, or marshmallow-jsonschema instead.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >= 2.7; the package targets older Python versions and may have compatibility issues with modern Python releases.
- Low install friction with three straightforward runtime dependencies.
- However, the package is abandoned—last commit was 2022-10-25 and no releases since 2019-10-05.

What it is and what it does
jschema-to-python is a command-line code generator that reads a JSON schema file and produces Python class definitions matching that schema's structure. It uses attrs, jsonpickle, and pbr as runtime dependencies to support the generated code. The tool accepts a schema path, output directory, and root class name, with optional hints files to control code generation behavior.
The package is positioned as a bridge between schema-first API design and Python development—useful when you have a JSON schema and want corresponding Python dataclasses without writing them by hand. However, it has been abandoned since late 2022 with no active maintenance, meaning it will not receive updates for Python version changes, dependency conflicts, or bug fixes.
Use it for
- Generate Python models from OpenAPI or JSON Schema specifications for API client libraries.
- Automate boilerplate class creation when working with schema-driven microservices.
- Convert external JSON schema definitions into Python code for data validation and serialization.
- Bootstrap Python projects that consume or validate JSON data against a known schema.
