Import of Gnumeric spreadsheet files is supported in LibreOffice (in experimental mode). However, Gnumeric is not listed in the list of supported file types in "File" -> "Open" -> "File Types". Please add "Gnumeric" *.gnumeric to the list of file types if "Experimental Mode" is switched on. Version: 4.1.4.2, Build-ID: 410m0(Build:2) Same in LO 4.2RC2
enhancement request. set status to NEW
Fixed now in LibreOffice 5.1. Gnumeric is in the list of file types that can be opened. If I remember correctly, Markus Mohrhard provided the improvement of the import filter and the patch.
