Usage with Docker
The jsonschema-markdown
command is also available as a Docker image. To use it, you can mount the schema file as a volume.

Usage as a library
To use it as a library, load your JSON schema file as Python dict
and pass it to generate.
The function will return a string with the markdown.
import jsonschema_markdown
with open('schema.json') as f:
schema = json.load(f)
markdown = jsonschema_markdown.generate(schema)
Features
Partially inspired by json-schema-for-humans, this project does not currently support all features of JSON Schema, but it should support:
- Required fields
- String patterns
- Enumerations
- Default values
- Descriptions and titles
- Nested objects
- Basic OneOf, AnyOf, AllOf functionality
- Arrays
- Integers with minimum, maximum values and exclusives
- Boolean values
- Deprecation notices (searches for case-insensitive
deprecated
in the field description)
Caveats
- This project is still in early development, and the output may change in the future.
- Custom definitions are expected to be in the same file as the schema that uses them,
in the
definitions
or$defs
parameter at the root of the document.
