As I've written elsewhere in these threads, SIGIL is remarkably adept at pasting content that you've copied from WORD. Select the whole WORD document and cut, then paste into a new SIGIL html file in Book view. The result is a pretty decent approximation of what you had in Word. You'll want to redefine <p> to get indented paragraphs without intervening space. Best of all, you don't get any of the horrible html that WORD insists on exporting.

Going the other way: Suppose you find you want to export your epub to WORD. I was astonished at how well this can work in SIGIL. Merge your chapters together, select all, cut, and then paste into WORD. Paragraph structure, italics, curly quotes are all preserved.
