body: <p>When I try this with <code>roo gem</code>:</p>
  
  <pre><code>irb(main):001:0&gt; require 'roo'
     =&gt; true
  irb(main):002:0&gt; oo = Excel.new("C:/Users/Abash/Desktop/test1.xls")
  
  **NameError: uninitialized constant Excel** from (irb):2

  <pre><code>irb(main):001:0&gt; require 'spreadsheet'
     =&gt; true
     irb(main):002:0&gt;Spreadsheet.client_encoding = 'UTF-8'
     =&gt; "UTF-8"
