The font is registering as the same size (for instance, if it's 10 point on my end, it is also 10 point when I get the file back from my boss). But the overall size of the worksheet changes and the fonts seem to stay relative to the field they are in, so it seems they are getting bigger and smaller too. So, in other words, if there is a word "Blender" with apparently 3 spaces after it in the column, the next time I get the file it will still look like it has 3 spaces after, but the whole thing is a different size.
