Reference notes

How JSON validation works

JSON validation checks whether text conforms to the JSON grammar.

Useful validation feedback explains common issues such as trailing commas, single quotes, unescaped control characters, and mismatched brackets.

JSON validator examples

Valid JSON includes objects, arrays, strings, numbers, booleans, and null.

Invalid examples should show why {name: "Ada"} is not strict JSON: the property name must be quoted.

JSON validator FAQ

JSON validation confirms syntax, not business meaning. A syntactically valid object may still be missing fields required by an application.

Schema validation can be added later as a separate capability if the Engine supports it.

JSON validator references

Reference material should cover the JSON grammar and official data types.

Future notes can explain how parser error locations differ between libraries.

JSON validator developer examples

Developer examples should show validating request bodies, configuration snippets, and copied API responses.

Examples should avoid automatically repairing invalid JSON unless the user explicitly chooses formatting behavior.
