How it works

Both documents are parsed with JSON.parse() and validated in this page. The validator supports the common JSON Schema keywords: type, enum, const, numeric and string bounds, pattern, required, properties, additionalProperties, items, contains, uniqueItems, allOf/anyOf/oneOf/not, if/then/else, dependencies and local $ref resolution. Nothing is uploaded.
