Hi Guys:

I want help in converting .txt files in my current matlab directory into .csv files while retaining the original names of the files. Most importantly, The code should also save the .csv files into the same folder or directory as the .txt files. I really appreciate it.

Is this just renaming them or does data have to be extracted from the files and written in the csv?

They need to be extracted and then saved with the .csv extension.

在 MATLAB Online 中打开

dinfo = dir('*.txt');
filenames = {dinfo.name};
for K = 1 : length(filenames)
  thisfile = filenames{K};
  [basedir, basename, ~] = fileparts(thisfile);
  newfile = fullfile(basedir, [basename '.csv']);
  convert_to_csv(thisfile, newfile);
end

Where convert_to_csv is a function that you would write that would take a particular input file name and a particular output file name and do whatever is necessary to extract the data from that .txt and write it to the csv.

You have not told us anything about the structure of the .txt so we do not know what needs to be done. Some .txt files are very easy to convert to csv, but other .txt files can take a lot of work to convert to .csv
