Hello; I am inexperienced in coding. can anyone help me please about my attached file. I would like to transpose some some data with a specific format in txt. The data may vary but i have made an example for you to understand it with an example output. The data in sheets and number of sheets in csv may change based on data i have. In attached csv file there is only one sheet for first set, however there are some other sheet in same format, but i could not add to csv file as multiple sheets. Any kind of help is appreciated. Thank you

csv files can't have "sheets" since they're just flat text files. Only .xlsx files can have sheets.

S = fileread('input.csv');
newS = regexprep(S, {'^\*PART[^\n]*\n', '^(\d)'}, {'', '*PART\r\n$1'}, 'lineanchors');
fid = fopen('sample output.txt', 'w');
fwrite(fid, newS);
fclose(fid)

it is not important to have the information of sheets in the data. I just want it have all the data in one txt file. Thank you

in_filename = 'input.xlsx';
out_filename = 'output.txt';
[filepath, basename, ext] = fileparts(in_filename);
[status, sheets] = xlsfinfo(in_filename);
if isempty(status)
error('file "%s" is not a readable excel sheet', in_filename);
end
allnum = [];
for idx = 1 : length(sheets)
thissheet = sheets{idx};
num = xlsread(in_filename, thissheet);
allnum = [allnum; num];
end
numcols = size(allnum, 2);
fmt = ['*PART\n', repmat('%f,', 1, numcols-1), '%f\n'];
[fid, msg] = fopen(out_filename, 'wt');
if fid < 0
error('Failed to open output file "%s" because "%s"', outfile, msg);
end
fprintf(fid, fmt, allnum.' ); %transpose is important
fclose(fid);
