Removing file extensions

Question

I have 200 documents that I have individually renamed, without the file extension. Suddenly today, every document has a file extension on it (.docx). The problem is that the extension takes up room in how the name displays - as it only displays so many digits. So now half the name of the docs aren't displayed and some longer names are totally obscured. All I did was go into those folders and print off a couple of those documents. Suddenly there they were - the extensions. On every document.

How do I get rid of the file extensions all together, in one step? There's no way I want to keep renaming each individual document each time this happens. Thanks for any help.

I'm on a Mac Sonoma 14.4.1 with Windows 10.
