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
or
csvwrite('dataset.csv', scaled)
