这里有许多将数据转换为CSV的解决方案，但几乎所有的解决方案都有各种各样的注意事项，即在不出错的情况下正确格式化数据类型。

为什么不使用一些经过验证的东西:Papa Parse

Papa.unparse(data[, config])

然后只需结合这与本地下载解决方案之一在这里，如。@ArneHB的那个看起来不错。

这个库有很大帮助:https://www.npmjs.com/package/json-to-csv-in-browser

它自动将json数组转换为csv文件，甚至为您提供下载功能，以防您想提示web用户下载csv文件。 它用很少的代码就像一个魅力。

import { JsonArray, download } from 'json-to-csv-in-browser'

const arr = [
    {name : ` vader`, age : 53},
    {name : "what", age : 38},
    {name : "ever", age : 22}
]
const jsonArray = new JsonArray(arr);
const str = jsonArray.convertToCSVstring();
download("my.csv", str);

干杯!

编辑:再测试一下，如果你的值上有逗号，它就不能很好地工作了

这是基于已接受答案的修改答案，其中数据将来自JSON。

            JSON Data Ouptut:
             0 :{emails: "SAMPLE Co., peter@samplecompany.com"}, 1:{emails: "Another CO. , ronald@another.com"}


            JS:
            $.getJSON('yourlink_goes_here', { if_you_have_parameters}, function(data) {
            var csvContent = "data:text/csv;charset=utf-8,";
            var dataString = '';
             $.each(data, function(k, v) {
                dataString += v.emails + "\n";
             });

            csvContent += dataString;

            var encodedUri = encodeURI(csvContent);
            var link = document.createElement("a");
            link.setAttribute("href", encodedUri);
            link.setAttribute("download", "your_filename.csv");
            document.body.appendChild(link); // Required for FF

            link.click();
        });

下面是一个Angular友好的版本:

  constructor(private location: Location, private renderer: Renderer2) {}

  download(content, fileName, mimeType) {

    const a = this.renderer.createElement('a');

    mimeType = mimeType || 'application/octet-stream';

    if (navigator.msSaveBlob) {

      navigator.msSaveBlob(new Blob([content], {
        type: mimeType
      }), fileName);
    }
    else if (URL && 'download' in a) {

      const id = GetUniqueID();

      this.renderer.setAttribute(a, 'id', id);
      this.renderer.setAttribute(a, 'href', URL.createObjectURL(new Blob([content], {
        type: mimeType
      })));

      this.renderer.setAttribute(a, 'download', fileName);

      this.renderer.appendChild(document.body, a);

      const anchor = this.renderer.selectRootElement(`#${id}`);

      anchor.click();

      this.renderer.removeChild(document.body, a);
    }
    else {
      this.location.go(`data:application/octet-stream,${encodeURIComponent(content)}`);
    }
  };

这个解决方案应该适用于Internet Explorer 10+， Edge，新旧版本的Chrome, FireFox, Safari， ++

已接受的答案不能在IE和Safari中使用。

// Example data given in question text var data = [ ['name1', 'city1', 'some other info'], ['name2', 'city2', 'more info'] ]; // Building the CSV from the Data two-dimensional array // Each column is separated by ";" and new line "\n" for next row var csvContent = ''; data.forEach(function(infoArray, index) { dataString = infoArray.join(';'); csvContent += index < data.length ? dataString + '\n' : dataString; }); // The download function takes a CSV string, the filename and mimeType as parameters // Scroll/look down at the bottom of this snippet to see how download is called var download = function(content, fileName, mimeType) { var a = document.createElement('a'); mimeType = mimeType || 'application/octet-stream'; if (navigator.msSaveBlob) { // IE10 navigator.msSaveBlob(new Blob([content], { type: mimeType }), fileName); } else if (URL && 'download' in a) { //html5 A[download] a.href = URL.createObjectURL(new Blob([content], { type: mimeType })); a.setAttribute('download', fileName); document.body.appendChild(a); a.click(); document.body.removeChild(a); } else { location.href = 'data:application/octet-stream,' + encodeURIComponent(content); // only this mime type is supported } } download(csvContent, 'dowload.csv', 'text/csv;encoding:utf-8');
