title: How to Validate a CSV file
body: <p>I want to validate a CSV file.</p>
  
  <p>The condition is that There are 9 columns, separated by commas, like this:</p>
  
  <pre>
  something1,some[thi]ng2,some/thing3,so"meth"ing4,somet'hi'ng:5,something6,something7,something 8,something9</pre>
  
  <p>What is a best way to check if I have those 9 columns in every line when they could by empty like: </p>
  
  <pre>,,,,,,,,</pre>
  
  <p>but structure should be OK.</p>
