Hello Everyone,
I have text file like one_1.txt, one_2.txt, one_3.txt, ....one_1000.txt..
where one_1.txt looks like below. I want to save data in individual excel sheet (high_1.xlsx) with 5 columns, say first coumn save 1 to 40, second coumn save 0.0125 to 0.9875, soon. Then I want to average value like C3 (which is 492.275 in high_1.txt) from all files high_2.xlsx, high_3.xlsx and save into another excel sheet (Average.xlsx). Actually, I want to average each cell over multiple excel files. How can I do this in Matlab?
one_1.txt include data as follows:
1 0.0125 473.825 293.313 1.10803
2 0.0375 472.725 327.064 1.07873

Hi Ankit,
Split your work into writing a code for a single file and use that same code to loop over all files. Questions related to importing data and processing multiple files are frequently asked, so you should use the search tool to find an answer.

For first step of converting the txt files into excel files use readtable and writetable functions. Loop all the required files and perform the operation.
As an example
n=100; % number of txt files
for i=1:n
filename=["one_" num2str(i) ".txt"];
T=readtable(filename);
outputfilename=["high_" num2str(i) ".xlsx"];
writetable(T,outputfilename)
end
For calculating the average use mean function on required column and store that in new file using writetable, writecell
