Zooming Pixelates Text in Excel

Hello all,

I have several files that would be extremely helpful to view zoomed out. However, the text becomes rather pixelated at around 65% zoom, and the numbers are entirely unreadable at about 50% (see pictures).

At first I was thinking this had something to do with scaling, but my monitor's settings are on default 100%. I also looked all throughout Excel's "View" options, but I couldn't find anything there either. On my 13" MacBook Pro I can zoom way out to under 10% and the fonts are still legible (though they are very tiny). So, I assume that this Windows machine should be able to do something similar, but I can't figure out what's wrong.

Thanks!
