If each chapter is formatted as an h1-h6 tag or marked with a unique style, you could use Sigil to insert split markers. For example, if all your chapter headings are formatted as <h1> tags, you'd use:

Find:<h1

Replace:<hr class="sigil_split_marker" /><h1

Then select Edit > Split at markers.

Simply select all files in the Sigil Book Browser, then right-click them and select Merge. This will merge all files into a single file.
Then use Find & Replace to add split markers and select Edit > Split at markers. – Jan 10 '18 at 15:34

For anyone coming here from an online search, you can also do cmd + enter to split at cursor position. – Dennis Hackethal Aug 19 '21 at 01:43
