2. LibreOffice has some extensions to create epub, e. g.

A LibreOffice link that could probably be more useful.

Atlantis Word Processor directly exports to EPUB, but you have to style it correctly, a la MSWord.

Yes, you have to buy a license.

The Word/LibreOffice to Calibre pipeline that was mentioned earlier is really the sweet spot for non-technical people. The key thing I'd emphasize is teaching them to use heading styles consistently (Heading 1 for chapters, Heading 2 for sections) — that alone gets you a working table of contents and clean chapter breaks after conversion. For the final polish, Sigil is hard to beat. The live preview makes CSS tweaks much less intimidating than editing blind, and the find/replace with regex is invaluable for cleaning up the little formatting artifacts that Word tends to leave behind.

Coming late to this thread but the advice about heading styles is spot on. In my experience, the biggest mistake people make when creating EPUBs from Word is not using proper styles — they'll manually bold and enlarge text instead of using Heading 1/Heading 2. That single habit change gets you a proper table of contents and chapter breaks after Calibre conversion without any extra work. And for cleaning things up afterward, Sigil's live preview plus regex find/replace is the most efficient workflow I've found. Makes CSS edits much less daunting than working blind.

In my experience the biggest mistake people make when creating EPUBs from Word is skipping proper styles — they manually bold and enlarge chapter titles instead of using Heading 1 and Heading 2. That one habit change alone gives you a proper table of contents and chapter breaks after Calibre conversion with zero extra effort. For cleanup afterwards, Sigil with its live preview and regex find-and-replace is the most efficient workflow I've found for fixing the formatting quirks Word leaves behind.

calibre also has a preview and regex in the editor. So which editor you use is your choice. calibre's editor may have more features then you realize. Some use both calibre and Sigil because they each do something the other doesn't or does something better.

Another thing is to watch the video I embedded in this thread. It gives a good overview of using Word with styles.
