Expand compact JSON-LD into fully qualified IRIs

JSON-LD expansion resolves @context terms, @id references, and type coercion into a canonical graph representation using absolute IRIs. Expanded form is useful for comparing documents, debugging vocabularies, and feeding data into RDF pipelines.

What this tool does

Paste a compact JSON-LD document that includes an @context block. The converter runs the W3C JSON-LD expansion algorithm and outputs a normalized graph with fully expanded property names and node identifiers.

When to use expansion

  • Inspect the semantic meaning behind compact schema.org markup.
  • Normalize linked data from different vocabularies before merging graphs.
  • Debug context mappings that produce unexpected compact keys.
  • Prepare JSON-LD for downstream RDF or triple-store tooling.

To shorten expanded IRIs back into readable keys, use JSON-LD to Compacted. For sample-driven TypeScript models from plain JSON, try the JSON to TypeScript POJO Generator.

Frequently Asked Questions

Does my JSON-LD leave the browser?

No. Expansion runs locally using jsonld.js. Your linked data is processed on your device only.

Must my input include @context?

Compact JSON-LD usually includes @context so terms can be expanded to IRIs. Documents that are already expanded may pass through with minimal changes.

Why is expanded output harder to read?

Expansion intentionally replaces short keys with full IRIs to create an unambiguous semantic representation. Use compaction when you need a human-friendly view.

Can I expand remote JSON-LD URLs?

This tool processes pasted JSON-LD text only. Fetch remote documents first, then paste the JSON content into the input panel.
