How to Use the Schema / JSON-LD Markup Generator

Pick a schema type, fill in a few fields, and get a ready-to-paste JSON-LD block — everything runs in your browser, with no signup and nothing uploaded.

1
Pick a Schema Type
Choose FAQ, Article, or HowTo. FAQ is shown first since it's the markup AI engines quote most when answering questions directly from your page.
2
Fill In the Fields
FAQ: type your questions and answers, adding more pairs as needed. Article: headline, author, date, and an optional image. HowTo: a name plus your numbered steps.
3
Generate & Check Validity
Click Generate and the tool builds a real JSON-LD object, parses it back to confirm it's valid JSON, and shows a clear ✓ Valid or ✗ Invalid badge before you copy anything.
4
Switch to Pro for More Types
Unlock Product, Breadcrumb, and Review schema, combine several types into one @graph block, save configurations as named profiles, and preview an approximate rich-result snippet.
5
Copy or Download the Script Tag
Copy the ready-made <script type="application/ld+json"> tag straight to your clipboard, or download it as a file, then paste it into your page's HTML.

Every field you type, every schema object built, and every saved profile stays in your own browser. Nothing is uploaded to a server, and Pro's saved profiles live only in this browser's local storage.

Schema / JSON-LD Markup Generator: Build FAQ, Article & HowTo Structured Data Free, Right in Your Browser

Quick answer: Pick FAQ, Article, or HowTo, fill in the fields, and get a ready-to-paste <script type="application/ld+json"> block, checked for valid JSON before you copy it. Pro mode adds Product, Breadcrumb, and Review schema, plus a way to combine several types into one @graph block. Everything runs in your browser, nothing is uploaded, and FAQ schema is shown first because it's the structure AI answer engines quote most.

Structured data, written as JSON-LD and following the vocabulary at schema.org, is what tells Google, Bing, and AI answer engines exactly what a piece of content is, not just what it says. Most people only hit this when a schema markup checker like Google's Rich Results Test flags a page as missing it, or when they go looking for a json-ld schema generator because hand-writing nested JSON by hand is slow and easy to get wrong. This tool is built for that moment: pick a schema type, fill in plain fields, and get back correct, parseable JSON-LD without touching a curly brace.

Every schema type here, FAQPage, Article, HowTo, Product, BreadcrumbList, and Review, is built from the real schema.org vocabulary those types require, not a simplified approximation. Required fields are enforced before you can generate anything, and the resulting JSON is run through an actual parse check so a broken script tag never reaches your clipboard.

1Why FAQ Schema Comes First

Ask ChatGPT, Perplexity, or Google's AI Overviews a direct question, and the answer they quote back usually traces to a page with clear question-and-answer structure. FAQPage schema makes that structure explicit to a machine instead of implicit in prose, which is why it's the single highest-leverage schema type for AI citation, and also why it's the default tab here rather than something you have to dig for. A faq schema test against your own page, whether that's a browser extension or a manual check in Google's Rich Results Test, is only meaningful once the markup exists, and that's what this tab builds: a set of question and answer pairs turned into a valid FAQPage object with one click.

2Article & HowTo: The Classic Rich-Result Pair

Article schema tells search engines the headline, author, and publish date behind a piece of content, which feeds into how it can appear in Google News, Discover, and standard article rich results. HowTo schema breaks a process into numbered steps that Google can render directly in search results as an expandable, step-by-step card. Both tabs here ask for only what each type actually requires: Article needs a headline, an author, and a publish date, with an image as an optional extra; HowTo needs a name and at least two real steps, since a "how to" with one step isn't a process worth marking up.

Simple Mode covers the three schema types most pages actually need. Pro Mode, currently free to use, is built for a page doing more than one job at once: a product page that also answers common questions, or a blog post with both an Article block and a breadcrumb trail, combined into a single @graph the way a developer would hand-code it.

None of these need a developer on standby. A content writer who knows their FAQ copy, an author who knows their own byline and publish date, or a store owner who knows a price and a rating can fill in plain fields and walk away with correct JSON-LD, instead of searching for a schema generator merkle users built templates around years ago and hoping the syntax still holds up.

5Combining Schema Into One @graph (Pro)

A real page often needs more than one schema type at once: an Article block for the post itself, a FAQPage block for the questions at the bottom, and a BreadcrumbList for where the page sits in the site. Hand-coding that means merging several JSON-LD objects under a single @graph array without breaking any of them. Pro Mode's Combine tab does this automatically: it checks whichever schema types you've already filled in across the other tabs, lets you pick which ones to include, and outputs one valid @context plus @graph block ready to drop into your page's <head>.

Privacy Note

Every field you type, every schema object this tool builds, and every saved profile in Pro Mode is handled entirely by JavaScript running in your own browser. Nothing is uploaded, stored, or transmitted to a server at any point, and saved profiles live only in this browser's local storage.

6Frequently Asked Questions

Is this schema markup generator free, and does it work as a schema markup validator too?
Yes, building schema is free with no signup. It isn't a schema markup validator in the sense of crawling a live URL, but every schema object it builds is checked with a real JSON.parse() call before the Copy or Download buttons unlock, so you always know the JSON-LD is syntactically valid before you paste it.
What's the difference between this tool and a schema markup checker like Google's Rich Results Test?
A schema markup checker, such as Google's Rich Results Test, reads markup that already exists on a live page and reports whether Google can parse it. This tool does the opposite: it builds the markup in the first place, from the fields you fill in, as a ready-to-paste <script type="application/ld+json"> block. Most people use a generator like this one first, then run the result through a checker afterward.
Why does FAQ schema come first instead of Article or HowTo?
FAQ schema is the structure AI engines such as ChatGPT, Perplexity, and Google's AI Overviews lean on most when they quote a direct answer back to a user, because a question-and-answer pair maps cleanly onto a question someone actually asked. Article and HowTo schema still matter for classic rich results, so they're one tab away, but FAQ is the one most worth setting up first if your goal is AI citation, not just search snippets.
Can I generate a JSON-LD schema generator output for more than one schema type on the same page?
Yes, that's what Pro Mode's Combine tab is for. It reads whatever you've already filled in on the Article, FAQ, HowTo, Product, Breadcrumb, and Review tabs and merges the valid ones into a single JSON-LD block using schema.org's @graph syntax, which is how a real page combining several schema types would actually ship it.
Is anything I type uploaded to a server?
No. Every field, every generated schema object, and every saved profile is built and stored entirely by JavaScript running in your own browser. Saved profiles use this browser's local storage only, and nothing is ever transmitted anywhere.

Built on the real schema.org vocabulary. Every field this tool asks for maps directly to properties defined at schema.org and documented in Google Search Central's structured data documentation, rather than a simplified or invented schema of this tool's own.
