title: how to import any type of file(CSV,XLS,XLSX,txt) into jqgrid
body: <p>I want to import from an .xls file into jqgrid...</p>
  
  <p>I have an idea but I don't know how to implement it, because no direct method is there for import,</p>
  
  <ol>
  <li>select the file from particular location</li>
  <li>convert the file into java object like (list,array list etc)</li>
  <li>then convert java object to json object</li>
  <li>pass that json object in grid model inside jquery grid.</li>
  </ol>
  
  <p>suggest me how to implement...</p>
