Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
As a fellow Office user, I get your frustration!
Your .wps file won’t open in Microsoft 365 because it’s from 'Microsoft Works', which Microsoft stopped supporting in 2009. Being an older format, Microsoft 365 just doesn’t recognize it.
The good news is you can try converting it to a .docx file using an online tool like FreeConvert (https://www.freeconvert.com/wps-to-docx).
I can’t say for sure if it’ll work, since I don’t have any .wps files to test myself, but it’s worth a shot!
