I refuse to import text. It’s not worth the hassle and added style sheet garbage.

I get around this hyphen problem by selecting all in word, pasting all into a text edit document (set to plain text), then copy/pasting all into an INDD text box.

Also, I use Plainclip.app extensively. It sits in your dock and unformats all clipboard text on click. https://www.bluem.net/en/projects/plain-clip/
