How to Format N-Triples RDF Data - Step by Step Guide

Step 1

Input Your N-Triples Data

Start by adding your N-Triples data. Whether it's from a database export or a text file:

•
Paste directly: Copy your N-Triples and paste it in
•
Upload a file: Click "Upload" to select a .nt file
•
Try the sample: Click "Sample" to see an example

Example: Unformatted N-Triples Input

Here's what messy, unformatted N-Triples look like (hard to read):

<http://example.org/person/1> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://schema.org/Person> .<http://example.org/person/1> <http://schema.org/name> "Dr. Alice Johnson" .<http://example.org/person/1> <http://schema.org/email> "[email protected]" . <http://example.org/person/1> <http://schema.org/jobTitle> "Data Scientist" .<http://example.org/person/2> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://schema.org/Person> .
Step 2

Automatic Validation & Formatting

As soon as you add your N-Triples, the formatter (powered by N3.js) cleans it up automatically. Here's what happens:

•
Checks syntax: Makes sure each triple is valid RDF
•
Adds consistent spacing: Each triple on its own line, properly formatted
•
Groups related triples: Sorts by subject so related data stays together
•
Counts triples: Shows you how many triples are in your data

Example: Beautifully Formatted Output

The same data, now cleanly formatted and easy to read:

<http://example.org/person/1> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://schema.org/Person> .<http://example.org/person/1> <http://schema.org/name> "Dr. Alice Johnson" .<http://example.org/person/1> <http://schema.org/email> "[email protected]" .<http://example.org/person/1> <http://schema.org/jobTitle> "Data Scientist" .<http://example.org/person/2> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://schema.org/Person> .
Step 3

Export Clean N-Triples

Get your beautifully formatted N-Triples ready to use:

•
Copy to clipboard: Quick copy for pasting anywhere
•
Download as .nt file: Save for import into Apache Jena or Virtuoso
•
Convert to other formats: Use our RDF Format Converter if you need Turtle or JSON-LD

Example: Using Formatted N-Triples

Your formatted N-Triples are ready for:

→
Triple Store Import: Load into Apache Jena, Virtuoso, GraphDB, or Amazon Neptune for SPARQL querying
→
Data Integration: Merge with DBpedia, Wikidata, or custom knowledge graphs
→
Streaming Pipelines: Convert to Jelly-RDF for high-performance RDF streaming applications

Frequently Asked Questions

What is N-Triples format?

N-Triples is the simplest RDF format - one triple per line. It's widely used for bulk imports into RDF databases because it's easy for computers to process quickly.

Does the formatter validate syntax?

Yes! It checks each triple for errors and will tell you if something's wrong. It uses N3.js to make sure everything is valid.

Can I convert N-Triples to other formats?

Yes! Use our RDF Format Converter to change N-Triples to Turtle, JSON-LD, or RDF/XML.

Does formatting change my data?

No! Formatting only makes it look better. All your triples and data stay exactly the same - just easier to read.

Can I use this for large files?

We recommend files under 10MB for browser formatting. For larger files, consider using command-line tools.

Is this formatter free?

Yes, it's completely free! No sign-up, no limits.
