Structured data without the syntax headaches

This generator builds valid JSON-LD structured data for the schema types you actually use. Hand-writing nested JSON-LD is error-prone — a missing comma or wrong @type silently breaks rich results. Pick a type, fill in your data, and copy a clean <script type="application/ld+json"> block that validates.

How it works

JSON-LD describes your page using the schema.org vocabulary inside a script tag. Every object needs a @context (the vocabulary) and a @type (what the thing is), then type-specific properties:

{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [
    { "@type": "Question", "name": "Q?",
      "acceptedAnswer": { "@type": "Answer", "text": "A." } }
  ]
}

For list types the tool builds arrays: FAQPage maps each Q | A line to a Question/Answer pair, and BreadcrumbList maps each Name | URL line to a positioned ListItem. All values are JSON-escaped so quotes and special characters in your text stay valid.

Tips and notes

  • Match your structured data to what users actually see on the page — Google penalises markup that describes hidden or absent content.
  • Validate every snippet with Google’s Rich Results Test or the Schema Markup Validator before deploying.
  • You can include multiple JSON-LD blocks on one page, one per entity (for example Organization plus BreadcrumbList).
