Old notes from now discontinued Tranglos Keynote (.knt) can be exported to several other document formats with the original program. This also includes document formats from MS Word (.doc, .docx). Sadly, it appears that no other program is capable of handling these notes, so using the original program remains your only option for this conversion.

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.
