title: How can I read an Excel File with JavaScript (without ActiveXObject)
body: <p>My friend asked me to make for a simple application to generate charts (bar, curves) from an Excel file. I opted to use JavaScript as a language since I know already the powerful chart.js. However before using chart.js, I have to gather data from the Excel file. So how to read an Excel file via JavaScript? </p>
  
  <p>After some research I have managed to do this with Internet Explorer with (using ActiveX), but I need it to work across browsers.</p>
