About

The XAVERT Markup Generator creates Schema.org structured data in JSON-LD format for common website entities and content types.

Main Features

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.
