Privacy details

Structured data studio processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Optional settings apply only to this tab.

Your result

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

Structured data studio explained

Paste a JSON-LD document to inspect node types, named identifiers and references within the document. Missing in-document definitions stay visible, and repeated identifiers are listed for review. No context URL is contacted.

Next: JSON formatter

A worked example

A Person node with name Ada appears as one typed node. A reference to its @id is marked as defined only when that identifier also has a description in this document.

Before you use the result

A local structure inspector, not a full JSON-LD processor, Schema.org validator or rich-result eligibility check. Remote contexts, aliases and semantic inference are not resolved. Repeated identifiers can be intentional.

Next: JSON Schema validator
