如何使用ember.js上传XLSX文件并将其转换为JSON

Question

I am trying to allow the user to upload an XLSX file to be converted to a JSON or CSV file to be parsed through on the back-end. I am using node.js, and tried several packages including the read-excel-file ( https://github.com/catamphetamine/read-excel-file/blob/master/README.md )

readXlsxFile(file).then(function(data) {
let jsondata = JSON.parse(data);
-do something with jsondata-
});

Answer 1

The usual place to look for add-ons would be Ember Observer but the options available seem have a status of Work In Progress - they might be a useful place to look though to get some inspiration for how to proceed.

There are plenty of options on npm . You can import one of those into your project using the new add-on ember-auto-import or, if you'd rather do the hard work yourself, the Ember guides provide some guidance on manually importing .

Answer 2

You can use js-xlsx . Add it as bower dependecy and add its imports to your ember-cli-build file as:

app.import('bower_components/js-xlsx/dist/jszip.js');
app.import('bower_components/js-xlsx/dist/xlsx.min.js');

Handle it as the documentation's parsing-workbooks section shows. ( handleFile function is explaining it well.)
