Writing JSON Schema manually is time-consuming and error-prone. This tool parses your input JSON data, automatically infers its structure and data types, and generates a document compliant with the JSON Schema Draft 07 specification. JSON Schema is a metadata format for describing JSON data structures, defining validation rules such as field types, required fields, and value ranges.
Q: Can the generated Schema be used directly in a production environment?
Yes, but we recommend adding business-specific validation rules. The automatically generated Schema only contains basic type inferences.
Q: How does it handle fields containing null values? The tool will mark null fields as nullable (nullable: true) while preserving their original data type inference.
Please ensure the input JSON format is valid. Complex business rules need to be added manually. We recommend using a complete and representative data sample.
For API design, we recommend generating a base Schema first, then adding business constraints like minimum/maximum. Typical example: User registration data usually requires the email field to comply with the RFC5322 format, which requires manually adding the format: "email" rule.
