JSON-LD Schema Markup Generator

Pick a Schema.org type, fill the essential fields, and copy a ready-to-paste <script type="application/ld+json"> block or raw JSON. It is generated entirely in your browser, and FastMinify never fetches your URL, audits live rich results, or promises all 800+ Schema.org types. This is SEO structured data, not JSON Schema API validation.

JSON-LD Schema Markup Generator
Build Schema.org structured data for rich-results snippets. FastMinify never fetches your live page, and the JSON-LD is paste-ready from form fields only.

Developer notes

outputFormat wraps JSON in <script type="application/ld+json"> or emits raw JSON for CMS/build pipelines. jsonFormatting toggles pretty vs compact whitespace; includeNullFields controls null vs omitted optional keys. idStrategy can omit @id, set it from the type’s primary URL field when absolute, or use a custom @id text field. Warnings are structural only — they do not block copy. Validate eligibility with Google Rich Results Test after deploy. Distinct from the JSON Schema Validator (API payload validation against a JSON Schema document).

Options

  • Output format

    Script tag for HTML <head> paste vs raw JSON for CMS imports and build pipelines.

  • JSON formatting

    Pretty 2-space indent for human review or compact output for minimal inline script bytes.

  • Include null fields

    When on, optional empty fields appear as null keys; when off, they are omitted for lean JSON.

  • @id strategy

    Omit @id, derive it from the type’s primary URL field when absolute, or supply a custom @id.

When this is the right tool

Ship a static or JAMstack page that needs FAQ, Product, or Breadcrumb JSON-LD in <head>. Draft structured data without npm packages, SaaS fetchers, or copying brittle blog snippets. Complete the SEO hub workflow: meta tags → robots.txt → sitemap.xml → JSON-LD.

JSON-LD Schema Markup Generator FAQ

Local Schema.org generator

Does FastMinify fetch my URL or validate live rich results?

No. Output is built only from form fields in your browser. Nothing is fetched, crawled, or sent to Google. After deploy, use the external Google Rich Results Test linked on the page.

Is this the JSON Schema Validator?

No. This tool generates Schema.org metadata for SEO (JSON-LD in HTML). The JSON Schema Validator checks API payloads against a JSON Schema document, which is a different job in the JSON tools hub.

Which Schema.org types does v1 support?

Six types: WebSite, Organization, Article, Product, FAQPage, and BreadcrumbList. Only the essential fields are covered, not all 800+ Schema.org types.

Does the output guarantee Google rich results?

No. The tool shapes structurally valid JSON-LD locally. Google decides eligibility and appearance in search after deploy, so use Rich Results Test externally, not inside FastMinify.

Can I import JSON-LD from my live page URL?

Not in v1. Paste fields manually or restore a shareable link. URL fetch and HTML head import are out of scope for this honest, browser-only generator.
