Browser-local structured data workbench

Schema Markup Generator & JSON-LD Checker

Build tidy, copy-ready JSON-LD for seven practical page types, then preflight your own markup for syntax, structure, and common eligibility mistakes. No signup, upload, proxy, or invented rich-result promise.

Private by design. Names, prices, addresses, job details, and pasted code are processed only in this browser tab: the tool makes no data requests and stores or uploads none of those values. As on other public pages, the shared site analytics may measure the page visit without receiving field contents.

Build your markup

Choose the type that matches the main visible content of one page. A red asterisk marks fields this generator needs to produce its supported shape.

Generated JSON-LD

Choose a type, complete its fields, then generate your markup.

    Use the output without overclaiming it

    1. Match the page

    Only mark up facts that visitors can find on that page. A product offer needs the real current price; an event needs a genuine event page; a job must be open and provide a visible way to apply.

    2. Install one coherent block

    Paste the script-tag version in the page head or body. Before adding it, check whether your CMS or SEO plugin already emits the same entity so you do not create contradictory duplicates.

    3. Validate after publishing

    Run the final page through Schema.org Validator and, for Google-supported appearances, Rich Results Test. Valid data can make a page eligible; it never guarantees a rich result or ranking change.

    Supported scope

    GeneratorWhat this tool builds and checksImportant boundary
    ArticleArticle, BlogPosting or NewsArticle with author, images, dates and optional publisher.Google currently describes applicable article properties as recommended rather than a universal required list.
    ProductOne Product with one truthful Offer, price, currency, availability and identifiers.No reviews, ratings, variants, shipping or return policies; do not fabricate them.
    LocalBusinessA conservative subtype, PostalAddress, opening hours and optional coordinates.Build a separate truthful entity for each physical location.
    EventPhysical, online or mixed attendance with dates, status, location and organizer.Google’s Event rich-result shape requires a physical Place. Online-only and mixed modes are Schema.org-only here and receive a recommendation, never a Google-oriented clean pass.
    JobPostingOnsite or remote role, hiring organization, dates, location/region and optional salary range.Content policies, application access, logo dimensions and whether a role is still open require page-level review.
    BreadcrumbListOrdered ListItem nodes from checked label/URL rows.The order must mirror the page’s real navigation hierarchy.
    OrganizationIdentity, official URL, logo, profiles, contacts and optional address.Usually belongs on the home/about page, not repeated with conflicting values sitewide.

    Validation and privacy limits

    The local checker confirms JSON syntax, basic JSON-LD containers, absolute web URLs, supported nested shapes, and a maintained subset of Google-oriented field rules. It does not download Schema.org, crawl your page, execute page JavaScript, verify that URLs resolve, compare markup with visible content, apply every vocabulary range, or predict a search result. Unsupported types are identified but receive only generic structure checks. Entered values are not uploaded or saved; normal shared site analytics may still measure that this page was visited.
