Schema Markup Generator

Generate valid JSON-LD structured data for Article, Product, FAQ, LocalBusiness, Recipe, Event and more — with a ready-to-paste script block. Built in your browser; nothing is uploaded.

Runs entirely in your browser — nothing you type is uploaded.

This tool runs in your browser. Please enable JavaScript to use it — the guide below explains what it does.

Note: the markup is generated in your browser with JavaScript. With JavaScript off you can read this guide, but the tool controls will not appear.

Generate JSON-LD structured data

This tool builds valid JSON-LD Schema.org markup entirely in your browser — no external validation service and no network request. Choose a schema type, fill in the fields that apply, and copy either the JSON-LD object or a ready-to-paste <script> block. The markup is produced with JSON.stringify, so it is always well-formed JSON.

How it works

  1. Choose a schema type — the form fields change to match it.
  2. Fill in the details — required fields are marked; leave anything that doesn't apply blank.
  3. For FAQ pages, add as many question-and-answer pairs as you need.
  4. Click Generate schema, then copy the JSON-LD or the complete script block.

Supported schema types

  • Content — Article, BlogPosting, NewsArticle, WebPage, FAQPage.
  • Commerce — Product, SoftwareApplication.
  • Entities — LocalBusiness, Organization, Person.
  • Other — Event, Recipe.
  • Two outputs — a clean JSON-LD object and a ready-to-use script block.

Practical tips

Only describe what is genuinely on the page — the markup should match the visible content. Fill in as many relevant properties as you can, since more complete, accurate data is more useful. After generating, paste the script block into your page and test it with a rich-results or structured-data testing tool to confirm it is eligible for the features you want.

Limitations

Valid markup makes a page eligible for rich results but does not guarantee them — search engines decide whether and how to display them. This tool covers common properties for each type rather than every possible field, and it does not fetch or verify your URLs and images.

Privacy

Everything runs locally in your browser. Your input is never uploaded, stored or shared, and the tool makes no network requests.

Frequently Asked Questions

What is Schema markup and JSON-LD?
Schema.org markup is structured data that helps search engines understand your content. JSON-LD is the recommended format — a small block of JSON, usually placed in a script tag in the page head, that describes the page or entity.
Does adding this markup guarantee rich results?
No. Valid structured data makes a page eligible for rich results, but search engines decide whether and how to display them. Use markup only where it accurately describes the page or entity.
Which schema types are supported?
Article, BlogPosting, NewsArticle, WebPage, FAQPage, Product, LocalBusiness, Organization, Person, Event, Recipe and SoftwareApplication. The form fields adapt to the type you choose, and FAQPage lets you add multiple questions.
How do I add the markup to my site?
Click Copy script to copy the complete script block, then paste it into your page — typically in the head or body. You can also copy just the JSON-LD object. This tool only generates the markup; it does not add it to your site.
Is my input uploaded or validated online?
No. The JSON-LD is built entirely in your browser using JSON.stringify. Your input is never uploaded, stored or shared, and the tool makes no network requests. To confirm eligibility, test the output in your preferred rich-results testing tool.
