It works — sort of. (I'm reviewing the free version. If I upgrade to the Pro version, I'll come back and revise this.) It's a multi-stage operation that takes some time to set up, but the developer gives clear instructions. The free version doesn't include source file names, but there's a developer's blurb at the end of each file you merge, so you can work it out. It preserves at least font size and color. But it DOES NOT PRESERVE COMMENTS, which are essential in my use case. I imagine that people who create a lot of documents to merge into a single final one often include comments, and need them in the merged version. Almost surely not the developer's fault, because in Google Sheets, comments are not accessible to GAS. I tried copy and paste ⌘A⌘C → ⌘V, and that didn't copy comments, either. Thanks, Google! Luckily, comments DO survive export to .docx format. I should've used Word to begin with — but with Word, you still have to copy and paste. Inserting as a file keeps formatting, but not comments; inserting as an object doesn't preserve formatting.
