A CSV on the Web based XLSX parser with RDF/JS Stream interface
npm install rdf-parser-csvw-xlsx
A CSV on the Web based XLSX (Excel file format) parser with RDF/JS Stream interface.
Consult the rdf-parser-csvw documentation about usage, which provides the technical foundation of this parser.
Note that this parser is much slower and needs more memory than the pure CSV based parser. If you need performance, convert the data to CSV first and use the rdf-parser-csvw parser.
