Just a quick "heads up" for anyone who might be interested. I work on a Windows 10 computer, using Microsoft Word. I know that both Amazon's KDP and Barnes & Noble Press allow you to upload a Word file and they automatically create the e-book for you. That's okay for when you get to the end of the writing and editing process, but I sometimes like to take a preview of the e-book while I'm still futzing around. Microsoft offers a free DOCX to EPUB converter, which I have downloaded and installed. It works -- but it's not great. The two biggest flaws I have found (so far) are that (1) it doesn't start new chapters on a new page; and (2) it loses formatting for italics. The first can be addressed by breaking into the EPUB file and manually editing the CSS script. The italics can be fixed only by going through the entire manuscript, line by line, to add the tags where needed. Not good. I have been playing with a free office software suite from Germany called Softmaker FreeOffice. It's available for Windows, Mac, and Linux -- and they have a version for Android currently in beta testing. FreeOffice Textmaker includes a function to export to EPUB. I just tested it, and it fixes both of the problems the Microsoft converter has. It properly starts chapters on a new page, and it renders italic text in italics. What it lost was the center justification of the text on the title page, but that's a lot easier to fix than having to read through an entire manuscript to manually insert italics tags. Not all converters are created equal, apparently. Next up will be to try Libre Office again, but I don't hold out much hope. I tried that one once before and I wasn't pleased with the result.
