Upon running the following code:
filename = 'Bitcoin_Data_Lab_9.xlsx';
A = xlsread(filename);
T = readtable(filename)
The outputs are similar to the spreashseet but not identical. A has completely deleted the dates column and only shows the numerical ones, while T has every column but every date which was in the dates column is now NaN (my dates are formatted as (mm/dd/yyyy). How can I make it so that the dates are displayed (preferably with xlsread but either function is acceptable).
For reference, the excel file is attached above.

my guess is you're going to want to interpret the dates column as a string. going off of this, it would be something like
opts = detectImportOptions(filename);
opts = setvartype(opts, 'Dates','string');
T = readtable(filename, opts)

Definitely looked hopeful, but this is what the first rows of my table were output as:

Could you try like below?
filename = 'Bitcoin_Data_Lab_9.xlsx';
A = readcell(filename);
T = readtable(A)

After running this, I am met with the following error messages:
Error using readtable (line 198)
File input must be a non-empty character vector or string scalar.
Error in Untitled (line 4)
T = readtable(A)
