title: Creating a multidimensional-array in JSON from CSV files
body: <p>I am trying to create a JSON file from multiple CSV files. The files would be named like bugs.csv and executions.csv.</p>
  
  <p>Example of the bugs.csv files:</p>
  
  <pre><code>month,,1,2,3,4
  app1,ownerA,42,34,38,12
  app2,ownerA,13,23,24,43
  app3,ownerB,48,72,39,62
  </code></pre>
  
  <p>Example of the executions.csv files:</p>
  
  <pre><code>month,,1,2,3,4
  app1,ownerA,1200,1500,900,1000
  app2,ownerA,600,650,660,540
  app3,ownerB,2750,3500,3000,3200
  </code></pre>
  
  <p>What I would like the JSON to look like:</p>
  
  <pre><code>[{"Application":"app1",
  "Owner":"ownerA",
  "bugs":[[1,42],[2,34],[3,38],[4,12]],
  "executions":[[1,1200],[2,1500],[3,900],[4,1000]]},
  
  {"Application":"app2":,
  "Owner":"ownerA",
  "bugs": [[1,13],[2,23],[3,24],[4,43]],
  "executions":[[1,600],[2,650],[3,660],[4,540]]}]
  </code></pre>
