@Arijeet Sinha: loop over the folders, read the file data. What have you tried so far?

Very similar to the MATLAB documentation shows:
you will want to either use dir or sprint to get the folder names. Something like this should work:
P = 'directory where the 20 subdirectories are';
S = dir(fullfile(P,'*'));
S = S([S.isdir]); % remove files
S = natsortfiles(S); % optional
for k = 1:numel(S)
F = fullfile(P,S(k).name,'filename.txt');
S(k).data = dlmread(F); % or whatever function reads your data.
end
All of your data will be in the structure array S.

Folder = 'C:\Base\Folder\';
FileList = dir(fullfile(Folder, '**', 'YourFile.xlsx'));
Data = cell(1, numel(FileList));
for k = 1:numel(FileList)
File = fullfile(FileList(k).folder, FileList(k).name);
Data{k} = readtable(File); % Or however you import the data
end
