# JSON Schema Toolkit Validate, generate, and convert JSON Schemas with zero dependencies. ## Commands All commands use `scripts/json_schema.py`. ### Generate Schema from Sample Data ```bash python3 scripts/json_schema.py generate --input sample.json python3 scripts/json_schema.py generate --input sample.json --output schema.json echo '{"name":"Jo","age":25}' | python3 scripts/json_schema.py generate --input - ``` Auto-detects string formats (email, date-time, date, uri, ipv4). ### Validate JSON Against Schema ```bash python3 scripts/json_schema.py validate --schema schema.json --data data.json ``` Reports all validation errors with JSON paths. Exit code 1 on failure. ### Convert Schema to Code ```bash python3 scripts/json_schema.py convert --input schema.json --format typescript python3 scripts/json_schema.py convert --input schema.json --format python-dataclass python3 scripts/json_schema.py convert --input schema.json --format markdown --name User ``` Supported formats: `typescript`, `python-dataclass`, `markdown`. ## Supported Validation Keywords type, enum, required, properties, additionalProperties, items, minLength, maxLength, pattern, minimum, maximum, minItems, maxItems, format. ## Stdin Support Use `--input -` to pipe JSON from stdin for both `generate` and `validate --data`.
