Cloud products silently change format all the time, and AFAIK the formats aren’t documented.
This list has KeyNote, for example, but claims it’s a XML based format. It hasn’t been for years. I also wouldn’t know how to read a Google sheets file without Google’s software (but maybe I didn’t search hard enough)
Older formats also are getting lost. For example, try opening a MacWrite file or a Word 1.0 file. MacWrite has the additional problem that part of the file (a 16-character etaoin shrdlu string used to compress the text) is in the resource fork. Preserving that is easy, but also easily forgotten.
And even if you can open a file today, today’s tools may do a better job converting to PDF or .mp4 than those we’ll have a hundred years from now. File converters that see little testing for rare formats.
