Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To use the Article Schema Builder, choose whether you are marking up an Article or a BlogPosting, then fill in the core fields such as headline, author, publisher, and publish date. The tool assembles a single valid JSON-LD block from those inputs as you go.
When the fields are complete, copy the generated markup and paste it into the head of your page or your CMS schema field. Everything is generated locally in your browser, so the content you enter never leaves your device.
Sometimes the problem is not validating schema you already have, it is generating a clean block in the first place. The Article Schema Builder handles that directly, giving you correct structure without hand-writing JSON-LD or copying from a half-matching example.
This pairs well with a markup preview or validator: use the builder to create the block, then validate it before publishing. The builder focuses on producing correct, copy-ready output rather than auditing existing markup.
Short answers for the questions people usually have before trying a utility like this.
Yes. The Article Schema Builder supports both Article and BlogPosting schema types, so you can match the markup to the kind of page you are publishing.
No. The builder stays form-based and local; you enter the fields manually and it generates JSON-LD in your browser without fetching a live page.
Yes. It is free to use with no signup, and the JSON-LD is generated entirely in your browser so nothing you enter is uploaded.
Copy the generated block and paste it into your page head or your CMS schema field. It is ready to use, and you can validate it with a structured-data testing tool before publishing.
