About this tool
Validate structured data before release so schema markup generators, CMS exports, and hand-written JSON-LD do not ship with avoidable syntax or field issues.
Schema Validator is built for people who need to validate json-ld and structured data markup without leaving the browser. Validate structured data before release so schema markup generators, CMS exports, and hand-written JSON-LD do not ship with avoidable syntax or field issues. On this page, the main job is narrow and practical: parses json-ld objects, arrays, and @graph payloads directly in the browser, then checks required fields for common schema types like article, faqpage, product, organization, and breadcrumblist.
- Parses JSON-LD objects, arrays, and @graph payloads directly in the browser.
- Checks required fields for common schema types like Article, FAQPage, Product, Organization, and BreadcrumbList.
- Outputs normalized JSON-LD you can copy back into production after fixing issues.
How to use Schema Validator
Enter page URLs, metadata, markup, or audit exports into the tool above, check the result, and export clear recommendations you can push back into templates or CMS fields. If you are checking an edge case, start with "Does this schema validator support JSON-LD arrays and @graph?" and verify the output against that scenario.
When this tool is useful
- Validate JSON-LD generated by your CMS or schema generator before publishing.
- QA article, FAQ, product, or organization markup during a technical SEO review.
- Normalize and inspect structured data copied from multiple plugins or templates.
- Compare hand-written schema against what plugins or CMS fields actually export.
Practical tips
- Treat this as a fast pre-publish check, then verify live pages in external rich result testing tools when eligibility matters.
- Keep URLs absolute and required fields complete before worrying about richer optional properties.
- If your page uses multiple schema nodes, validate the combined @graph instead of isolated fragments.
- Use one final normalized copy as the source of truth so multiple teams are not editing divergent schema snippets.
