Why Do So Many Publicly Available Datasets Open In Such Inconvenient/unusable Formats?

Trying to just view the CDC datasets, and the only format it seems to open in is text document. Why!?!? I can’t tell a single thing that’s going on, not even the variables being measured, because it just looks like blocks of text arranged haphazardly in the notepad app

Some other datasets from GitHub contains EDF files and text files again, which are also super inconvenient

Like where is the option for csv or spreadsheet, or basically anything that’s readily viewable and understandable? Why isn’t that the default? I was expecting that viewing the data files would be the easier part of trying to write a research paper, but no

Also if anyone knows how to get this CDC dataset into a viewable format, please let me know! Thanks
