switching from IMac Catalina to a windows PC

You would need to manually export them from Numbers and Pages into Excel and Word documents on the iMac.

From the File Menu in Pages and Numbers select the "Export To" option.

I don't believe Libre Office can directly open Pages or Numbers files, and Microsoft Office definitely cannot do that.

LibreOffice only officially supports opening (as you say) simple Pages '09, Numbers '09, and Keynote '09 documents.

That said, I just dropped a Numbers spreadsheet originally created with Numbers 3.6.1 and last updated with Numbers v10.1 onto the LibreOffice 7.5.4 Dock icon. LibreOffice opened the spreadsheet and everything was intact except that it removed the formulas. Then I took the same spreadsheet, opened it in Numbers v13.1, changed a single number in a cell, and saved it. The same approach with LibreOffice as above would not open the spreadsheet with intelligible content.

You can see the version history of a non-package folder Pages, Numbers, or Keynote document in the Terminal using this syntax:

Look into the Free LibreOffice, it handles MS Office files like Word & Excel, & Page Layout…

No idea how complex it works with or which versions but in Mojave opened a fairly simple .numbers file in LibreOffice. Not sure if any of the Pages Export types would help, it has a few.

I know. Just pointing out that LibreOffice may simply not open a pages file at all. Have not tried it on a Windows computer though.

Exporting the documents from Pages to Word or some other format LibreOffice or MS office is more likely to open would be a better strategy as I said above.

I tried to open a Pages file in LibreOffice on my Mac and all I get is an empty document.

It's just simple text.

FWIW, there is no direct conversion.

Actually LibreOffice can open at least simple .numbers files.

Yes, I know. I didn't say it was "good" at it. Only that it would open. 😎

As I mentioned in my first post, "FWIW, there is no direct conversion.".

For Pages, exporting is likely best. File>Export? Plain Text or RTF Text for that scenario.

Aha!:)
