<p>Open up your file using regular old vanilla <strong>Notepad</strong> that comes with <strong>Windows 7</strong>.</p>
<p>It will show you the encoding of the file when you click “<em>Save As…</em>”.</p>
<p>It’ll look like this:</p>
<p>Whatever the default-selected encoding is, that is what your current encoding is for the file.</p>
<p>If it is UTF-8, you can change it to ANSI and click save to change the encoding (or visa-versa).</p>
<p>There are many different types of encodings, but this was all I needed when our export files were in UTF-8 and the 3rd party required ANSI. It was a onetime export, so Notepad fit the bill for me.</p>
<p>FYI: From my understanding I think “<em>Unicode</em>” (as listed in Notepad) is a misnomer for UTF-16.</p>

<p>Far more Encoding options are available in NotePad++; should you need them.</p>
<p>Other (Mac/Linux/Win) Options:</p>
<p>I hear Windows 11 improved the performance of large 100+MB files to open much faster.</p>
<p>On the web I’ve read that Notepad++ is still the all around <em>large-file editor</em> champion.</p>
<p>However, (for those on <strong>Mac</strong> or <strong>Linux</strong>) here are some other contenders I found:</p>
<p>1). <a href="https://www.sublimetext.com/">Sublime Text</a></p>
<p>2). <a href="https://code.visualstudio.com/">Visual Studio Code</a></p>
