Dear E.J.Berry.
Thanks for using Microsoft products and posting in the community.
I understand that you can't open .wps files with the Office 365 version. I understand how you feel and will do my best to help you.
Files with the .wps file extension are Microsoft Works documents or WPS Writer documents. Microsoft Office 365 may not support opening these files directly.
Microsoft discontinued the Works document file format in 2006 and replaced it with .doc. The two are similar in that they both support rich text, tables, and images, but the .wps format lacks some of the more advanced formatting features supported by .doc and .docx.
If you have an older version of Microsoft Works software, try opening the file on that and saving it as another format. If you don't currently have this software installed, it may be difficult to obtain a copy of it given that it has been discontinued.
You can try converting .wps files to .docx or other Office-supported formats using some online file format conversion software.
Thank you for your support and understanding and please feel free to let me know if you have any further updates, thanks.
Best Regards,
