You can use tables from Kingsoft Office spreadsheets (.et) and use them to make a new MS Word document (.doc, .docx) via the default File ► Save as.. function in the program. It appears this is not only the most convenient way, but also the only possible as Kingsoft Office formats are not well support in other programs, if they are at all.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
