使用Angular.js将上传的csv文件对象转换为json对象

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.9/angular.min.js"></script>

<input type="file" ng-model="csvFile" />

angular.module('myApp', [])
  .controller('myController', function($scope) {
    $scope.convertCSVtoJSON = function() {
      var file = $scope.csvFile;
      var reader = new FileReader();

      reader.onload = function(e) {
        var contents = e.target.result;
        var lines = contents.split('\n');
        var result = [];

        var headers = lines[0].split(',');
        for (var i = 1; i < lines.length; i++) {
          var obj = {};
          var currentLine = lines[i].split(',');

          for (var j = 0; j < headers.length; j++) {
            obj[headers[j]] = currentLine[j];
          }

          result.push(obj);
        }

        $scope.jsonData = result;
      };

      reader.readAsText(file);
    };
  });

<button ng-click="convertCSVtoJSON()">Convert to JSON</button>

<pre>{{jsonData | json}}</pre>
