I have dataset in csv file. I have normalized it using

Data = rand(10, 20);  % Test data, use your data instead
minData = min(Data(:));
maxData = max(Data(:));
scaled  = (Data - minData) / (maxData - minData);  % Scaled to [0, 1]
scaled  = scaled * 2 - 1;  % Scaled to [-1, 1]

now the data is normalized, i want to save the normalized data in file again like csv, txt etc.

Do you see that the shown code is not relevant for your question? A scaled = rand(2,5) would be sufficient also.

You could use save() or csvwrite() or dlmwrite() or xlswrite()

I would suggest saving as a binary .mat file unless you need it as text for another program.

save() does not save in csv form.

save dataset.txt scaled -ascii -double %text format but not commas

csvwrite('dataset.csv', scaled)
