title: How to export or convert JSON to Excel in AngularJS?
body: <p>I'm extracting an array with 4 objects and each object has an array inside, from my kendo charts datasource, on my Angular project.</p>
  
  <p>The data inside each sub-object varies in size, but it always includes a timestamp, and 1-5 value fields.</p>
  
  <p>I need to export this array to an Excel file (.xls or .xlsx NOT CSV).</p>
  
  <p>So far I managed to download the JSON as a file on its own (both .json and unformatted .xls).</p>
  
  <p>I'd like for each object to be a book and in that book to have a formatting that has the timestamp in the first column, value 1 in another, and so on. The header for the columns should be timestamp, value1 name, etc (I'm translating these on the ui according to user preferences).</p>
  
  <p>How can I build this type of formatted .xls file using angular? I don't know a particular good library for this, that is clear on how to use it in Angular.</p>
