Schema.org JSON-LD Generator Online Free
Build standards-compliant Schema.org JSON-LD for six high-impact types — FAQPage, Article, LocalBusiness, SoftwareApplication, HowTo, and Product — from simple form fields, then copy the complete script tag ready to paste into your page head. Empty rows are filtered out automatically so the emitted JSON stays valid.

How to Use Schema.org JSON-LD Generator
- Step 1: Pick the schema type that matches the page: FAQPage for question lists, Article for posts, LocalBusiness for physical stores, and so on.
- Step 2: Fill only the fields relevant to that type; blank FAQ or HowTo rows are dropped from the output automatically.
- Step 3: Watch the generated JSON-LD script tag update live in the code panel below the form.
- Step 4: Click Copy to place the full <script type="application/ld+json"> block on your clipboard.
- Step 5: Paste it into the <head> of your HTML and validate with Google's Rich Results Test before deploying.
About Schema.org JSON-LD Generator
Structured data is a machine-readable vocabulary (Schema.org, jointly maintained by Google, Microsoft, Bing, and Yandex) that tells search engines what an entity is — not just what words appear on the page. JSON-LD (JavaScript Object Notation for Linked Data) is the format Google formally recommends: a JSON blob inside a script tag, decoupled from visible markup so it can be managed independently of the DOM. When validators and crawlers parse valid JSON-LD, pages become eligible for rich results such as FAQ dropdowns under a listing, article headlines with bylines and dates, local business cards with hours and address, and product snippets with price and availability. Each type this generator emits maps directly to those rich result families: FAQPage requires a mainEntity array of Question/AcceptedAnswer pairs; Article needs headline, author, and datePublished; LocalBusiness nests a PostalAddress; SoftwareApplication declares applicationCategory and offers; HowTo enumerates ordered HowToStep objects; Product attaches a Brand and Offer with priceCurrency. Producing this by hand invites syntax errors — a missing comma silently kills the whole block — so the tool serializes real objects through JSON.stringify, guaranteeing valid output every time. The script never executes anything; it is pure declarative metadata.
Frequently Asked Questions
Where do I paste the generated script?
Inside the <head> section of the target HTML page, as a normal <script type="application/ld+json"> element. It must be valid JSON — no trailing commas or comments.
Does adding schema guarantee a rich result?
No. Valid markup makes a page eligible, but Google decides whether to surface a rich result based on page quality, relevance, and historical performance for that query.
Why are some rows omitted from the output?
Incomplete FAQ or HowTo rows (missing question or answer text) are filtered so the emitted JSON stays schema-valid and does not include empty Question objects.
Is JSON-LD different from microdata?
Yes. Microdata embeds attributes inside HTML elements; JSON-LD keeps metadata in a standalone script tag. Google recommends JSON-LD because it is easier to generate and maintain without touching visible markup.
Does this tool validate against Google Rich Results Test?
The output follows the published schema.org types Google checks for each family. Always run the final page through the Rich Results Test to confirm page-specific eligibility.
