I'm looking for a method to verify that a .doc or .docx file that has been created in Microsoft Word, and then modified in Ubuntu (in my case, with LibreOffice) will look the same when I give it to people using Microsoft Word.
Unfortunately, they need the ability to edit it afterward, or I would just export the files as pdfs.
I can see that the files remain more or less the same, but what I'd like is to be able to check it every time before I send the file back. A 100% accurate viewer could solve this, or an on-line method.
Any (preferably easy-to-implement) ideas?
