best approach for editing MS docs is to use the auto conversion setting on the upload to google drive. (if you just upload to drive, you need to RHC (two finger tap) on the file and use “open with” google docs – this creates a converted copy on the google drive – it retains the original word doc though)
once converted, you can edit away.
If you need to send the file on to someone, you can use the “Email as attachement” function in the file menu where you can sepcify whether it should convert it back to a word doc, or pdf or open doc formate or rtf etc etc.
Much of the time if you think about it, pdfs are the best as there’s no need to send someone an editable doc.
However if it needs to be editable then sending them a link share to the google doc is a good idea as you can then collaborate on the same doc.
