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.
This SEO tool is built for pre-publish QA and implementation support rather than vague optimization advice. It helps teams check one search-facing signal cleanly before a page, template, or release goes live.
- 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 the relevant metadata, markup, URL set, or export data into the tool above, then review the checks and corrected output. Use the result to fix the source template, CMS field, or deployment rule before shipping changes.
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.
Why people use this tool
