title: Parse excel file with using Perl
body: <p>I'm quite new in perl, so I'm asking for tips for the problem below :
  I have a excel file and I want to search for specific words in column title (1st row) then if 
  it matches I extract the entire column and put it in a array (or whatever else).</p>
  
  <p>So in my array, I will have first column then 2nd etc... until the end of the search.</p>
  
  <p>I'm intending after that to read my array line by line to process data in order (I'm confortable for that part).</p>
  
  <p>thanks</p>
