Schema markup generator

Create a JSON-LD block for a Schema.org type with optional validated extra properties. Build a syntactically valid structured-data starting point for an article, product, organisation or another Schema.org type.

This generates syntactically valid JSON-LD. Search-feature eligibility still depends on the selected type, required properties and visible page content.

How to use the schema markup generator.

Add the requested inputs

Use the labelled fields in the workspace above. If example values are provided, try them first or replace them with your own.

Calculate and review

Use the main action when needed. The generator combines the required context and chosen type with entered fields, validates extra JSON and serialises one JSON-LD script block.

Try a worked example

Create an Organization object with its name, canonical URL, description and image, then add reviewed properties as JSON.

Check the assumptions

Valid JSON-LD does not ensure semantic accuracy or search-feature eligibility; requirements change and markup must match visible page content.
