About this tool
Builds a JSON-LD object for the selected type using the entered name, URL, description and image fields. Field suitability depends on the selected type; for example, an Article may need a headline that this generic form does not supply. This generates a draft, not full Schema.org validation or a decision about search-feature eligibility. Check the values against the visible page and the requirements of the consumer before publishing.
Everything is generated on your device with nothing uploaded. Nothing you enter is uploaded, and it keeps working offline once the page has loaded.
