Open a CSV or a JSON file and you can read it, more or less. A binary file doesn&rsquo;t. Open one in a hex editor and you see rows of numbers like <code>45 42 01 02 01 41 00</code>, and nothing tells you where one value stops and the next begins.</p> <p>That&rsquo;s because the meaning lives outside the file. Some program decided that the first two bytes are a magic number, the next byte is a version, the one after that counts how many records follow, and so on. The program knows. The file doesn&rsquo;t. If you want to read that file in another program, you need a copy of that knowledge.</p>
