How to load data from DAT file

Hi guys

can someone please help me with extracting data from .dat file. I wanted to attach an example file but it was to big.

I have tried the following codes but was unsuccesful. I would appriciate any input on this. Thanks!

fileID = fopen('example.dat');
OneByte = fread(fileID,'*ubit8');
A=double(OneByte);
%%
[filename directory_name] = uigetfile('*.dat', 'Select a file');
fullname = fullfile(directory_name, filename);
data = load(fullname)
%%
[FileName,PathName] = uigetfile('*.dat');
  localdir = dir;
  cd(PathName);
  load(FileName);
  cd('C:\Users\username\Documents\MATLAB\cd');

unfortunately there is no standard format for the .dat extension, so documentation about the file format would be needed.
