title: Split a 2 column CSV and save to different files
body: <p>I have a headerless CSV file in this format:</p>
  
  <pre><code>A,value for A
  B,value for B
  C,value for C
  ...
  </code></pre>
  
  <p>Now I need to split each row, saving each value to a separate file, named after the first column for the value:</p>
  
  <pre><code>File        Value
  A.txt       value for A
  B.txt       value for B
  C.txt       value for C
  </code></pre>
  
  <p>Notes: Values are non-English, so files have to be in UTF-8 encoding.</p>
