Switching to Office Libre, is there a way to make xls files open it?

In File Mgr I'm looking for a good way to switch default file opening to Office Libre. Maybe I just have to launch Libre first and open files individually from that file menu but I like to use File Manager sometimes. Also, I might like to change all .xls files in one sweep, not just one file at a time using right-click "open with," which is a little awkward. "Libre Office Calc" is listed there and seems to open only the spreadsheet portion of the suite, something I didn't know it could do. My Office 02 is becoming too unstable now to continue using it. I don't really want to join 365, just don't need it. Libre isn't listed in my Settings > Apps. Just looking for what is easiest. I've googled this first, have not seen a solution. Much of the guidance seems oriented around launching programs at startup, not sure I want to do that with Libre. Thank you, Don

Don,

Doesn't LibreOffice have a setting in its preferences to make it the default for all the file types it can handle?

Otherwise,
- you can right-click on an example of each relevant file type in File explorer,
- Open with,
- Choose another app
then
- set the checkbox for Always use this app &
- select/browse to the app you want.

Best of luck,
Denis

You right-click and choose 'Open with > Choose another app'. Tick the 'Always use...' box at the bottom.
