Schema.org Validator
Checks only whether JSON-LD has `@context` equal to `https://schema.org` and a nonempty `@type`. It does not validate type-specific properties or value types.
About this schema.org validator
Checks only whether JSON-LD has `@context` equal to `https://schema.org` and a nonempty `@type`. It does not validate type-specific properties or value types Validates and converts interface schemas client-side without transmitting private endpoint specifications.
API contract & interface schema logic
Compiles, validates, and simulates JSON Schemas adhering to IETF JSON Schema Draft-04, Draft-07, 2019-09, and 2020-12 standards via embedded Ajv validation engines. Performs structural type inference from concrete JSON instances, generating strict schemas complete with required arrays, type declarations, format annotations (e.g. date-time, uri, email, uuid), and constraint metadata. In reverse, it evaluates schema constraints to synthesize realistic mock JSON data payloads.
Worked schema conversion scenario
Scenario: An SEO analyst checks two basic fields in a JSON-LD object.
Sample input:
Processing: Checks only that @context is https://schema.org and @type is a nonempty string; it does not validate Schema.org types, properties, or rich-result eligibility.
Illustrative output:
Schema version & syntax constraints
Only these two fields are checked; it does not validate Schema.org type definitions, properties or values.

Frequently asked questions
What does Schema.org Validator actually validate?+
It parses JSON and reports valid only when `@context` is exactly `https://schema.org` and `@type` is a nonempty string. It returns the type value and an `issues` list for either local rule.
Can you show an input and its result?+
A JSON object containing `"@context": "https://schema.org"` and `"@type": "WebSite"` returns `valid: true`, `type: "WebSite"`, and no issues.
Which schema.org checks are absent?+
It does not validate whether the type exists, whether properties belong to it, cardinality, value formats, nesting, URLs, language, JSON-LD syntax beyond JSON.parse, Google rich-result rules or live page markup.
Does valid true mean rich results will appear?+
No. It only passes two local conditions. Search-engine crawl, rendering, guidelines, data quality, site trust and result presentation require separate evidence.
