xls2rdf

Create RDF data by editing formatted Excel spreadsheets. We use this at Sparna to populate knowledge graphs with RDF instances, edit SKOS vocabularies, SHACL specifications, even OWL ontologies.

Excel file structure

Complete documentation of the expected Excel sheets format can be found at https://xls2rdf.sparna.fr/rest/doc.html.

Implementations
