Frequently Asked Questions
What is a JSON Schema?
JSON Schema is a vocabulary that allows you to annotate and validate JSON documents. It provides a contract for what JSON data is required for a given application and how to interact with it.
How do I generate a schema from my JSON data?
Simply paste your JSON data into the input editor. The schema will be automatically generated based on your data structure, including data types, required fields, and patterns.
What information is included in the generated schema?
The generated schema includes data types, required properties, property descriptions, array item definitions, object structure, and validation constraints based on your JSON data patterns.
Can I customize the generated schema?
Yes! After generation, you can copy the schema and modify it to add additional constraints, descriptions, or validation rules as needed for your specific use case.
