How could I load and extract each individual column of this attached excel spreadsheet in matlab (excluding the headers only the values)?
Your assistance would be much appreciated

Have you tried the import wizard? It has lots of customisable options which you can make a script of at the end with the settings you want. Sorry if you have done this already..

[numbers, strings, raw] = xlsread(filename);
Then use indexing to pull out what you want.
column1 = numbers(1:41);
or whatever indexes you want. Beware that not all of those output arguments have the first row as the first row. For example numbers might have the first row as the third row in the workbook if the workbook doesn't have any numbers until row 3.

Give a name in an Open datatype Matrix-Form, then read the data into it
% Syntax is [ Name of variable in matlab to hold data]=xlsread('File name+extension')
I've just tested it.

No, this would replace the second column with NaN when the poster had requested to read everything.
readtable() gets much further, but when used without care, readtable() would replace M36 'UNSURE LOOK AT FILEPG' with NaN.

No, this would give nan for the second column and for M36 'UNSURE LOOK AT FILEPG'

I would take a look at "readtable" in MATLAB.
filename = 'myfile.xlsx';
T = readtable(filename);

My responses above imply that there is a text entry inside a numeric column. You would need readcell()
