The following review written by one of the Software Informer contributors applies to version 6.3
Kingsoft Office 18.104.22.1686 is an alternative to Microsoft Office.
The program will put three direct accesses in your desktop, for the three programs that are included in the package: Writer, Spreadsheets and Presentation.
This program includes "Writer", a word processor with an interface that resembles Word 2007. Writer can open Word documents, and save them as a file from any version of Word, an HTML file or a file with the native Writer format, .WPS.
"Spreadsheets" is the alternative to Microsoft Excel. It´s totally compatible with it, and can load Excel spreadsheets, modify them and save it again in Excel format (any version). You can, optionally, save in other formats as CSV or ETT. This last one is Kingsoft´s native format.
When using Spreadsheets, you can create and edit formulas just like you do in Excel. The program also provides cell autocompletion, tabbed windows, advanced charting and PDF export functionality.
"Presentation" is the Kingsoft´s version of Microsoft´s PowerPoint. It can load any file generated with that program, modify it and save in the same format. Presentation can read and play any PowerPoint presentation.
