Hi Tim, You’re doing something that is not supported by EDG out-of-the-box.
The EDG SS importers requires headers that are mapped to properties of the selected class into which to map each row. The fact that the import SS by pattern pops up with “Spreadsheet columns” and “Target Property” is a good hint. The documentation is at: https://doc.topquadrant.com/6.4/importing/ <https://doc.topquadrant.com/6.4/importing/> and then select Import Spreadsheet using Pattern. Options: 1 - Add column headers, then use Import Spreadsheet using Pattern 2 - Use an external tool to convert SS into RDF and then load that with EDG Import RDF (https://tarql.github.io/ <https://tarql.github.io/> is an example of such a tool) 3 - If you have access to TopBraid Composer you can open spreadsheets with “Semantic Tables”, do some conversion with SPIN/SPARQL/SHACL into ontology-based triples, and then EDG Import RDF.
