title: Reading xls file in Cocoa
body: <p>For my application development, I am using MAC OS, Cocoa and objective-c.</p>
  
  <p>In my application, I have following 2 requirements.</p>
  
  <p>1)Reading of xls file saved in 'UTF-16 Unicode Text' format.</p>
  
  <p>If I saves xls in above format, file type is becoming Text and extension is becoming .txt.</p>
  
  <p>I have used [NSString stringWithContentsOfURL:importURL encoding:NSUTF16StringEncoding error:&amp;readError]. </p>
  
  <p>Code is working fine without any issues.</p>
  
  <p>2)Reading of xls file saved in 'Excel Workbook' format.</p>
  
  <p>If I saves xls in above format, file extension is becoming .xls.</p>
  
  <p>Can any one suggest how to read xls file saved in 'Excel Workbook' format.</p>
