@Pete66: I recommend checking the Google Play Store for a PDF to Word doc converter, making sure to use download figures and user reviews to help you make an informed choice.
I just tried opening a pdf using Microsoft Word on my S23u and it opened it no problem. Also you can use Microsoft one drive to do the same. It will originally open it as read only and you just need to click on the edit logo top left(pad and pen logo) And it then converts to Word to edit.
