Export JSON Data to CSV File in AngularJs based on ui-grid's every row id

Export JSON Data to CSV File in AngularJs based on ui-grid's every row id

I need a CSV export option in angularjs 1.0 UI-grid's every row, where the user will click on that button, and based on the id server will respond a JSON based data then it should download in CSV format.

See the below image with Export CSV button.

enter image description here

Here's what I have tried so far:

Grid's column Definition 

         {
             field: "actions", "name": "Action",
             cellTemplate: '<button type="button" field-separator=","  ng-click="funcExport({{row.entity._id}})" csv-header="exportHeader" ng-csv="export" filename="Sample.csv">Export CSV</button>',
             width: "170"
         }

Export Function To CSV: Currently JSON data is not based on id but in static for demonstration.

    /*Function to export*/
var funcExport = function (id) {
    $scope.exportarray = [];
    $scope.exportHeader = [];
    $scope.export = [];
    $scope.exportHeader = ['Licence', 'Condition'];

    $scope.exportarray = [{ "Licence": "229973", "Condition": "Usage" }, { "Licence": "24141", "Condition": "Level" }];

    $scope.export = $scope.exportarray;
}

Any help would be appreciated!!

Solution

  • First convert JSON to comma separated CSV string then crate an anchor tag(a) set this CSV string as href fire a click, remove anchor tag.

    function convertToCSV(array) {

    var str = '';

    for (var i = 0; i < array.length; i++) {
        var line = '';
        for (var index in array[i]) {
            if (line != '') line += ','

            line += array[i][index];
        }

        str += line + '\r\n';
    }
    return str;
}

function exportCSVFile(headers, items, fileTitle) {

    items.unshift(headers);

    var csv = convertToCSV(items);
    var exportedFilenmae = fileTitle + '.csv' || 'export.csv';

    var blob = new Blob([csv], { type: 'text/csv;charset=utf-8;' });
    if (navigator.msSaveBlob) { // IE 10+
        navigator.msSaveBlob(blob, exportedFilenmae);
    } 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", exportedFilenmae);
            link.style.visibility = 'hidden';
            document.body.appendChild(link);
            link.click();
            document.body.removeChild(link);
        }
    }
}

/*Function to export*/
var funcExport = function (id) {

    var exportHeader = ['Licence', 'Condition'];

    var exportarray = [{ "Licence": "229973", "Condition": "Usage" }, { "Licence": "24141", "Condition": "Level" }];

    exportCSVFile(exportHeader , exportarray, 'download' );

}
