Hello and welcome - not sure if this is meant seriously, but
The files are apparently in the format (excel and JSON) that OpenLCA can import
this is as if saying the file is in XML format therefore it should be imported in any software that can import any XML format (EcoSpold, ILCD, EcoSpold2, to use only LCA format versions of XML...). openLCA supports JSON-LD (not JSON) in a defined structure, and expects the excel in a given structure for processes as well.
The files in the quartz database are more like EPDs (environmental product declarations) though, fully aggregated up to the LCIA result. We could prepare them but it is a bit of manual effort. Maybe you can contact us directly?
Thank you and best wishes,
