I was working on a spreadsheet, and decided to revert to an earlier version. Then it said the file was invalid. So I tried opening an earlier version on the timeline - but none of them will open. Is there any way to access one, so I don't have to re-do all my work from the last few years?

That doesn't look like Time Machine. That looks like Numbers. Time Machine.app is located in your Applications folder.
Presumably you have a backup system that backs up your Mac to another disk and/or online. (If you don't have one, you should have one.)

Thank you for that!
I had it on the Time Machine, but there was something similar from Numbers that had a restore option - where none of them would open.
Anyway, you have made my evening a lot happier!
Cheers,

I tried, but it said that it is damaged and can't be opened.
I tried the restore button, but only got this..
Sounds as if it's time to go to Time Machine (or whatever other backup system you are using) and 'restore' from there.
