JSON-LD Structured Data Generator

📖 About this tool

Structured data is the standard way for search engines to understand a page. Filled in correctly, it can earn rich results such as star ratings, expandable FAQ entries and breadcrumb trails. This tool turns ten common types into forms: pick a type and the fields switch automatically, with required fields starred, and FAQ and breadcrumb entries can be added or removed dynamically. The output is wrapped in script tags and ready to paste. Every generation is validated with a JSON parser, showing a green confirmation when it passes, so a missing comma or quote cannot slip through. Indentation can be 2 spaces, 4 spaces or a single compact line to match your code style. Everything runs locally. Typical uses include adding ratings and price data to product pages, generating FAQ accordions for help centres, completing publisher information on article pages, and adding address and opening hours to store pages.
