How to conver RAR archives to MS Word documents.
In most cases it's simply not possible to convert rar archive files to .docx Microsoft Word documents.
However, some .rar files might contain Word .docx documents inside the archive. You can simply extract all the files using WinRAR or other compression utilities capable to open and extract .rar compressed files.
In a word, direct rar to word conversion is not possible.
So don't expect any so-called rar to word converter or rar to word free online conversion tool available.
