Convert JSON-LD to N-Quads RDF format

N-Quads is a line-based RDF serialization format that extends N-Triples with an optional graph name component. Each line represents one RDF statement (quad) with subject, predicate, object, and graph terms.

What this tool does

Paste a JSON-LD document and the converter transforms it into N-Quads using the jsonld.js toRDF processor. The output shows every RDF quad extracted from your linked data document.

When to use N-Quads conversion

  • Inspect the RDF triples behind a JSON-LD document.
  • Feed linked data into RDF stores and SPARQL endpoints.
  • Debug JSON-LD markup by viewing the underlying graph structure.
  • Export semantic web data for tools that require N-Quads input.

For canonical RDF output, use JSON-LD to Normalized. To transform JSON-LD between compact and expanded forms, try JSON-LD to Expanded or JSON-LD to Compacted.

Frequently Asked Questions

What is the N-Quads format?

N-Quads is a W3C standard serialization for RDF datasets. Each line contains four terms (subject, predicate, object, graph) separated by spaces and ending with a period.

Does processing happen in the browser?

Yes. This tool uses the jsonld.js processor locally. Your documents are not uploaded to a server.

What is the difference between N-Quads and N-Triples?

N-Triples serializes RDF triples with three terms per line. N-Quads adds a fourth graph term, supporting named graphs and datasets with multiple graph contexts.

Can I convert N-Quads back to JSON-LD?

This tool converts JSON-LD to N-Quads only. The reverse operation requires an N-Quads to JSON-LD parser, which is a separate transformation using the fromRDF algorithm.

Why do some lines use blank node identifiers?

When JSON-LD contains nodes without explicit @id values, the processor generates blank node identifiers (like _:b0) to represent them in the RDF output.
