How to Produce Valid JSON Matching a Schema

To produce JSON that matches a provided JSON Schema, follow these steps: 1) Ensure the top-level structure matches the schema's declared type (usually an object or array). 2) Include all properties listed in the schema's "required" array and make sure each value matches the declared "type" for that property (e.g., string, number, boolean, array, object). 3) Do not add properties when "additionalProperties" is false; only include the properties defined in "properties". 4) Use proper JSON syntax: double-quoted keys and string values, no trailing commas, and correct nesting of arrays and objects. 5) When uncertain, use a JSON Schema validator (online or in your development environment) to check your output against the schema. Following these rules prevents common errors like missing required fields, type mismatches, unexpected extra properties, and malformed JSON.
