This schema markup generator builds valid JSON-LD structured data from a simple form. Pick a type, fill the fields, and copy the output — the markup updates live as you type, and nothing leaves your browser. It is the build half of a build → validate loop: generate the markup here, then send it to the schema validator to confirm syntax and rich-result eligibility.
What this generator builds
Each schema type maps to the schema.org required and key recommended properties, following Google's structured data guidelines:
| Type | Use it for | Key fields |
|---|---|---|
Article | Blog posts, news, editorial | headline, image, author, publisher, datePublished |
FAQPage | Q&A sections | question + acceptedAnswer pairs |
Product | A product with an offer | name, image, offer (price, currency), aggregateRating |
LocalBusiness | A physical location | name, address, telephone, openingHours, geo |
BreadcrumbList | Navigation trails | ordered name + URL rows (auto-positioned) |
How to use it
- Choose a schema type from the tabs.
- Fill the fields. Required ones are marked, and inline hints flag character limits, ISO-8601 dates, and currency codes.
- Copy the JSON, copy the ready-to-paste
<script>block, or download a.jsonfile. - Click Validate this markup to check it in the validator. Not sure which type you need? Start with the structured data planner.
