About
The XAVERT Markup Generator creates Schema.org structured data in JSON-LD format for common website entities and content types.
Main Features
- Generate Article, Product, LocalBusiness, Organization, WebSite, BreadcrumbList, FAQPage, Event, SoftwareApplication, VideoObject and Recipe markup.
- Use guided fields for nested authors, publishers, offers, ratings, addresses, locations and media.
- Create repeatable FAQ questions and breadcrumb items.
- Create Recipe ingredient and instruction arrays.
- Add advanced custom Schema.org properties with typed values.
- Check locally defined required and recommended implementation properties before deployment.
- Edit the generated JSON-LD directly and validate JSON syntax.
- Copy raw JSON-LD or a safe HTML script tag.
- Download structured data as a .jsonld file.
- Combine multiple entities with the built-in @graph builder.
- Open the official Google Rich Results Test or Schema.org validator for external validation.
Privacy First
Form values, generated JSON-LD, validation results and graph entities are processed locally in your browser. This tool does not require a third-party runtime and does not upload your structured data to XAVERT.
Local checks in this tool are implementation guidance, not a guarantee of Google rich-result eligibility. Search engines can change supported features and requirements over time, and valid structured data must accurately describe content that is visible on the page.
