Well, we'd have to see the form of the data in the spreadsheet and the error message but readmatrix doesn't return a cell arry; it returns a double array already -- any data in the spreadsheet that can't be interpreted as a valid floating point number will be returned as NaN.
m=readmatrix("C:\Users\Camilo\Desktop\data_raw_sample.xlsx");
m1=m(1:7,2:117);
will return the content of whatever is in the spreadsheet that is numberic in that region of the overall array; as noted, if some of the content of the file is non-numeric, those will be returned as NaN--but still in a double array.

Hi,
you can use import tool to import data from the spreadsheets. You can check if there are any NaN values too.
Hope this helps.
