Schema / JSON-LD Generator
Everything runs locally in your browser — nothing is sent to Google or any server, this only builds the JSON-LD markup.
How to use this Schema/JSON-LD generator
- Pick the schema type that matches your page content.
- Fill in the fields — required fields are marked with an asterisk (*).
- Copy the generated script tag into your page's head.
What is JSON-LD structured data?
JSON-LD is a way to describe your page's content in a machine-readable format that search engines use to understand context and, in some cases, show enhanced results like star ratings, FAQ dropdowns, or recipe cards directly in search. This tool builds valid markup and checks that the fields required by each type are filled in, but doesn't submit anything to Google to verify eligibility for rich results.
Does filling in every field guarantee rich results in Google?
No — valid structured data is necessary but not sufficient. Google decides whether to show rich results based on its own quality guidelines and may ignore markup even when it's technically correct. Test your final page with Google's Rich Results Test for eligibility, not just validity.
What does the required field check actually verify?
Only that the fields schema.org and Google commonly require for that type aren't empty — it doesn't check formatting like whether a date follows ISO 8601 or a URL is reachable. Always double-check the output before publishing.
