Requirement: I have REST WebService which is used to download a file from the Oracle UCM Server. The file extension is .csv

Now, when I invoke the REST WebService passing value of the valid parameter(s), it returns me the response in which the Document Content is Base64Encoded.

Thus, in this post, I will show you the JavaScript function that will Decode and Download the Document Content which is Base64Encoded.

Solution: For the solution of the above requirement we will use the below JavaScript code.

define([], function() {
  'use strict';

  var PageModule = function PageModule() {};

  PageModule.prototype.downloadFile_CSV = function(fileBytes) {
    var blob;
    blob = window.atob(fileBytes);
    var link = document.createElement("a");
    if (link.download !== undefined) {
      console.log('Susanto 4' + blob);
      link.href = 'data:text/csv;charset=utf-8,' + encodeURI(blob);
      link.target = '_blank';
      link.download = 'output.csv';
      link.click();
    }
  };

  return PageModule;
});

Hence, the solution to our requirement.
