title: Quick Excel generation
body: <p>I am building a categorized todo list (not as a feature or anything, just a quick, off-the cuff list). The list should be organized like this:</p>
  
  <pre><code>Category1  
  -----------Item1  
  -----------Item2  
  Category2  
  -----------Item1  (always the same items in each category)  
  -----------Item2  
  </code></pre>
  
  <p>So I have 2 text files, 1 with the categories and one with the items.</p>
  
  <p>If this were a database problem, I'd do a cartesian join, and the result would be pretty close to what I'm after.</p>
  
  <p>What I want to do is take these 2 files and spew out an Excel file where the first column is the category, and the second is the items.</p>
  
  <p>I started writing a little C# program to brute force this, but it just seems like I must be missing something -- is there a macro or maybe even a pithy PowerShell script that I could throw together to do this? It just seems like it should be so easy.</p>
