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
xls2rdf REST API
The Excel to RDF conversion service is accessible as an REST at http://xls2rdf.sparna.fr/rest/convert. It can work with online publicly accessible Google spreadsheets.

You can run the conversion from the command-line. See https://github.com/sparna-git/xls2rdf/wiki/Command-line-Excel-to-RDF-conversion
