It is well worth archiving. I recently helped typeset and publish (via Amazon) a diary written by one of my ancestors - https://amzn.to/3tmUI3l ($0.99 as that's the lowest price Amazon accepts, but you can read the preview to get the gist)

It is written by a homesteader in 1930s North Dakota, and she just relates bits of her life, her family, and her favorite recipes. Simple, yet it's still a remarkable way to evoke the life of the era, and worth preserving and sharing as you are comfortable.

On a related note, you may want to be sure you take care with the actual physical media you have as well. Time and improper storage can render things unreadable - archival boxes (https://www.archivalmethods.com/ and elsewhere) are made to be neutral/alkaline rather than acidic, and are the sort of things museums use to preserve artifacts.
