If you have the Image Processing Toolbox, you can normalize an array to between 0 and 1 by doing this:
normalizedData = mat2gray(data);

The format is not important with respect to the calculations. The values you want from your imported Excel data, and the minimum and maximum, retain their full precision regardless of how they are displayed.
If you want to change the Command Window format of your numbers, see the documentation for the format (link) function.

If you're using release R2018a or later, see the normalize function.

or rescale(). Is one better than the other?
