Important Notes


    
  
  • Generated structured data follows Schema.org specifications and Google's structured data guidelines as of early 2026. Always verify current requirements before deployment.
    • 
  
  • Rich results appearance in Google Search is not guaranteed — Google determines eligibility based on multiple factors including content quality and guidelines compliance.
    • 
  
  • This tool generates JSON-LD format, which is Google's recommended format for structured data.
    • 
  
  • The Import feature supports standard JSON-LD objects, @graph arrays, and script-tag-wrapped markup.
    • 
  
  • For Product and Event schemas, use the full schema.org URL for availability values (e.g., https://schema.org/InStock) — the tool generates these automatically from the dropdown.
    • 
  
  • Duration fields (prep time, cook time, etc.) accept hours and minutes and automatically convert to ISO 8601 format (e.g., PT1H30M).
    • 
  
  • All data remains in your browser. No data is sent to any server. This tool works offline after initial page load.
