Once you import this data into a MATLAB variable, there are multiple methods. One way is as follows, where x is the data and y is where I am storing the new data.
y = [x(:,1:4) x(:,23) x(:,5:22) x(:,24)]

No need for concatenation …
A = load('mydatafile.txt') % only numbers separated by spaces/tabs
A(:,[4 23]) = A(:,[23 4]) % switch columns 4 and 23
