Precise Text Review Duplication

I have a collection of customer reviews already saved in Word documents and I simply need every line transferred—exactly as-is—into a brand-new Word file. No edits, no re-formatting, no skipped punctuation: just a faithful copy that preserves all original layout, fonts, and spacing.
The task is straightforward but demands real attention to detail, as I will be running the final file through a diff checker to confirm nothing changed along the way. Your deliverable is one clean .docx containing the full set of reviews in the same order they appear now. If you have a fast, reliable method for duplicating Word content without introducing hidden styling issues, that will be a plus.
