Gnumeric is useful, but its GUI is very laggy (more laggy than LibreOffice Calc). Sadly, there NO fast & usable Qt-based alternative to Excell for Linux yet. As lightweight spreadsheet app for Linux I use Qt-based mtCellEdit[0], which does not support .xls/.xlsx formats & could not fully replace Excell too.
