title: How to use mongoimport to import csv
body: <p>Trying to import a CSV with contact information:</p>
  
  <pre><code>Name,Address,City,State,ZIP  
  Jane Doe,123 Main St,Whereverville,CA,90210  
  John Doe,555 Broadway Ave,New York,NY,10010 
  </code></pre>
  
  <p>Running this doesn't seem to add any documents to the database:</p>
  
  <pre><code>$ mongoimport -d mydb -c things --type csv --file locations.csv --headerline
  </code></pre>
  
  <p>Trace says <code>imported 1 objects</code>, but firing up the Mongo shell and running <code>db.things.find()</code> doesn't show any new documents. </p>
  
  <p>What am I missing?</p>
