What Structured Data does
Generate Schema.org JSON-LD for Organization, Article, Product, FAQ, and more.
How it works
Schema.org JSON-LD validators, OpenGraph spec compliance, and length-aware text inputs. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
