Free structured data generator & validator — www.jsonldtool.com
JSON-LD (JavaScript Object Notation for Linked Data) is a lightweight method of encoding structured data using JSON. It allows you to describe things like products, people, events, and organizations in a way that search engines understand — enabling rich results, knowledge panels, and enhanced search listings. Google recommends JSON-LD as the preferred format for structured data.
Here's how you describe a person using JSON-LD and schema.org vocabulary:
{
"@context": "https://schema.org",
"@type": "Person",
"name": "Jane Doe",
"jobTitle": "Software Engineer",
"url": "https://janedoe.dev",
"sameAs": [
"https://twitter.com/janedoe",
"https://github.com/janedoe"
]
}Unlock Google rich snippets — star ratings, prices, FAQs, and more — directly in search results.
JSON-LD lives in a <script> tag. No changes to your visible HTML markup required.
Pure JSON syntax that's easy to read, write, debug, and generate programmatically.
A W3C standard understood by Google, Bing, Yandex, and the entire semantic web ecosystem.
Connect your data to the global knowledge graph using URIs and schema.org vocabulary.
Product markup enables rich results with prices, availability, and ratings directly in Google Search:
{
"@context": "https://schema.org",
"@type": "Product",
"name": "Wireless Noise-Cancelling Headphones",
"brand": { "@type": "Brand", "name": "AudioTech" },
"offers": {
"@type": "Offer",
"price": "249.99",
"priceCurrency": "USD",
"availability": "https://schema.org/InStock"
},
"aggregateRating": {
"@type": "AggregateRating",
"ratingValue": "4.6",
"reviewCount": "1284"
}
}Schema.org provides the shared vocabulary that search engines use to understand web content. Maintained by Google, Microsoft, Yahoo, and Yandex, it defines hundreds of types — each with specific properties. This tool generates valid structured data using schema.org types so your data is recognized across all major search engines.
