Here is a general way of reading data from multiple files and performing operations on it.
I have changed the temperature values of the 2nd file to show as an example.
%Get all the files in the folder ending with .txt format
%Update the search text if there is a unique string related to all files
files = dir('*.txt')
%Run a for loop through all the files
for k=1:numel(files)
%Get the full path to the file
fullname = fullfile(files(k).folder, files(k).name);
%Read the data via readmatrix()
%As the output will only contain numeric values, not the text header
in = readmatrix(fullname);
%Write the data as a csv file, by changing the extension of the file
writematrix(in, replace(fullname, '.txt', '.csv'));
end
%Checking the output
type('File1.csv')
type('File2.csv')
