JSON-LD generation · bounded validation · local exports
Generate and validate structured data
Build common schema.org entities from empty fields or inspect pasted JSON-LD. OpenWebmaster checks syntax, graph structure, shared URLs, and supported type requirements without inventing page content or promising a rich result.

Ready to generate structured data.
Normalized output, supported type findings, and the deployment boundary will appear here.
Validate the rendered page, not only the draft
Use official validators
After deployment, run the page through Google’s Rich Results Test and the Schema.org validator.
Monitor production
Use URL Inspection and Search Console enhancement reports where applicable. Valid markup does not guarantee a special search appearance.
