Extract each value from rows of excel sheet for 40 iterations

I have an excel file which consists of 40rows and 1 column. All values are numerical. The values are for parameter named 'K'. There will be 40 iterations to be processed. For example, iteration1, K=row1column1; For iteration2, K=row2column1. Could anyone please assist on how to import the data, extract every value at different rows for each iteration? Thank you.

values = xlsread('Filename.xlsx');

for iteration = 1 : length(values)
    K = values(iteration);
    do something with K
end
