Calligra
Calligra is a free, office suite. Homepage https://www.calligra.org/
Its main advantage compared with LibreOffice/OpenOffice is smaller packages, which might run better on older/lower-spec hardware.
Its native document format is ODF and it can import/export a range of documents as well
- DOC(x)
- XLS(x)
- PPT(x)
- various graphics formats
- as well as some older formats
For General Users
The Windows version is experimental and not suitable for general users. Stable versions of the following are suitable alternatives
- LibreOffice 5.x http://www.libreoffice.org/ and
- OpenOffice 4.x http://www.openoffice.org/
Calligra is based on KDE desktop. Installation to other desktops is possible, requiring that approximately 80 MB of additional dependencies be downloaded
It is available in most major Linux distributions - most reliable way to install it would be via the distributions software manager.
- the version for KDE 4 is stable and perhaps the best choice for new users
- a compilation for Frameworks 5 is available but not completely stable and not recommended for viewing/editing important documents, at this juncture
- the Stage and Words modules are fairly usable
- Kexi and Sheets are usable for only simple databases and spreadsheets respectively
Documentation
A disadvantage, compared with LibreOffice and OpenOffice is that Help menu might not work. Help can be accessed from a separate web page: https://docs.kde.org/index.php?language=en&package=calligra from which PDF versions can also be downloaded
