Hi all..
I use the following code to export multiple columns in excel file to multiple text files (each column export as text file).
Walter Roberson wrote me the following code:
data = readtable('YourFileName.xls');
varnames = data.Properties.VariableNames;
for col = 1 : size(data, 2)
thisvar = varnames{col};
filename = sprintf('split_%s.txt', thisvar);
writetable( data(:,col), filename );
end
It works very well, but the only problem is each text file gets a header X1. Can I use this script without having header? The following screenshot explain more about the problem:

Consider using xlsread. It will separate the numeric values from the headers. You can still have access to the headers (and other non-numeric data) as well as the raw data by requesting 2 or 3 outputs from xlsread instead of only the first output.

I would do something like this:
[numeric_data, string_data, raw_output] = xlsread('YourFileName.xls');
The ‘numeric_data’ array will have your numeric data (possibly with NaN values in the first row that you can easily eliminate) as a double array. The headers (and other string data) will be in the ‘string_data’ output, and the entire contents of the file (as a cell array) will be in the ‘raw_output’ variable.
See if that does what you want.
