z = fopen('now1.txt'); c = textscan(z,'%s','delimiter','\n'); fclose(z);
t = regexp(c{:}{3},'\w*(?=\[)','match');
n = regexp(c{:},'(?<=\[)\d+\.\d+(?=\])','match');
out = array2table(str2double(cat(1,n{:})),'V',t);
Here now1.txt - text file with your data.

Hello Andrei,
For now i have single text file but in future if i take reading for my experiment sample, there will be 100 files inside a folder. Then I will need to loop through each text file and create seperate table for each file.
Is it possible to do this?

Hi,
when a file contains both a space, and a comma-separated and none value data as appendix,
solutionestimate = textscan(fid,'%s %s %f %s %s %s %s %s %s %f %f %f %f %f %f %f ' ...
, 'Delimiter', {' ',','} , 'MultipleDelimsAsOne', true,);
output does not work correctly. How can I solve this?
