What it is and what it does
jsonschema2md is a command-line and Python library tool that transforms JSON Schema definitions into clean, human-readable Markdown documentation. It parses JSON Schema files and generates formatted Markdown with property descriptions, types, and examples, making schema documentation accessible without manual writing.
The tool supports customization through options like example formatting (YAML or JSON), header levels, deprecated property visibility, and pattern-based filtering. It also supports multilingual output through babel integration, allowing documentation to be generated in different languages. The package includes both a CLI interface for direct file conversion and a Python API for programmatic use, plus pre-commit hook support for automated documentation generation in version control workflows.
Use it for
- Generate API documentation from OpenAPI/JSON Schema definitions for developer portals.
- Automate schema documentation in CI/CD pipelines to keep docs in sync with schema changes.
- Create multilingual documentation for international projects using babel translation support.
- Convert complex nested JSON Schemas into readable property tables for configuration file documentation.
- Integrate schema documentation generation into pre-commit workflows to enforce up-to-date docs.
