Hello everyone,
i have a for loop reading several files and doing some calculations for each of them. What i want to do is to save the results from every file in a seperate sheet on one excel file.
%% reading the files
files = dir('*.txt');
N=length(files);
for i=1:N
filename=files(i).name;
fid=fopen(filename);
data = textscan (fid, '%s %s %s %s %s %s %s %*s %*s %s %*s', 'headerLines', 2);
%%saving
R1=table (Time, beta, Sh, K, 'VariableNames' , {'Time', 'beta', 'Sh', 'K'});
F_xlsx=sprintf('results.xlsx');
writetable(R1,F_xlsx,'Sheet',[files(i).name]);
this is how i tried, but the it is filling the sheet only with the first file.

from the Matlab documentation "wrtitetable(T) writes table T to a comma delimited text file." As far as I am aware, this format doesn't support multiple sheets. I have used xlswrite when writing to Excel as you can define the sheet to be written to.

Have you done a step-by-step execution of your code to be sure that there are multiple files read?
Looking at it like that, I would just remore the square brakets to the sheet name:
writetable(R1,F_xlsx,'Sheet',files(i).name);
Personnally, I'm using writematrix() the same way on different tables without any problem.

I should have known better than to try exporting the CSV and writing VBA to import multiple files into different sheets within a common workbook. What a nightmare. This is a much more elegant solution, by orders of magnitude.
