Generated zip file doesn't unzip to reveal an excel file

[squirrelsRduck]

I'm using Macintosh El Capitan. I sent a zipped excel spreadsheet from the generate function's buffer, and i receive in browser. I unzip, and there's just a folder in there, with all the necessary data. But, the wrong format. It's a folder, that I cannot seem to open in Excel. Interestingly, I notice the Excel object that the 'save' method performs also generates a folder-like object in the filesystem. Not sure if it's the way Macintosh unzips files, or if it's a bug with the zip utility in 0.1.0 of this module. anybody know how to correct this?

this might be something to look into: client side utilization of the zip utility.

though, i had wanted to use the HTML5 download attribute to simply access the file as such. does anybody have sample code as to how to download a file without the HTML5 download attribute style, to make this work?

Old issue but this is resolved in https://github.com/protobi/msexcel-builder, a branch of this library. Example below:

function download(workbook, done) {
      var self = this;
      workbook.generate(function (err, jszip) {
        if (err) return callback(err);

        jszip.generateAsync({type: "blob", mimeType: 'application/vnd.ms-excel;'}).then(function (blob) {
          var filename = self.params.filename || "example.xlsx";
          if (navigator.msSaveBlob) { // IE 10+
            navigator.msSaveBlob(blob, filename);
          }
          else {
            var link = document.createElement("a");
            if (link.download !== undefined) { // feature detection
              // Browsers that support HTML5 download attribute
              var url = URL.createObjectURL(blob);
              link.setAttribute("href", url);
              link.setAttribute("download", filename);
              link.style.visibility = 'hidden';
              document.body.appendChild(link);
              link.click();
              document.body.removeChild(link);
            }
          }
          done(null)
        })
      })
    }
