Recommendations: - In the future, always keep backups of large scale projects, spreadsheets or otherwise
- If you don't have an "open-able" file, find out if it can be recovered. Spreadsheets come in many different file formats, but are probably based on XML or CSV. If this is the case, you may be able to open up the file as a binary or text file and salvage your data. This process might be a pain, but unless the file is "0 bytes" (meaning there was some form of I/O Error) you can probably get a majority of the data back.
- As for alternatives to OpenOffice-Spreadsheet and LibreOffice-spreadsheets, gnumeric is quite robust and compact. That said, all three are excellent programs. Any errors you encountered are generally rare, and may not have anything to due with the spreadsheet program itself - power fluctuation, driver errors, faulty hardware (HDDs, ram), system overload, etc...
