JavaScript/AngularJS: When reading excel row turns string with date, into date only value

I am using AngularJS to read and display the contents of an excel file.
When the excel file contains a row with a value such as:
“Finance Committee will need to meet prior to the board meeting on February 16“

The value gets converted into a date 2/16/01

After this piece of code gets executed (ProcessExcel)

$scope.DisplayFile = function () {
    var regex = /^[a-z0-9][-a-z0-9x20_!().:,]*.xlsx?$/i;
    if (regex.test($scope.SelectedFile.name)) {
        if (typeof (FileReader) !== "undefined") {
            var reader = new FileReader();
            //For Browsers other than IE.
            if (reader.readAsBinaryString) {
                reader.onload = function (e) {
                    $scope.ProcessExcel(e.target.result);
                };
                reader.readAsBinaryString($scope.SelectedFile);
            } else {
                //For IE Browser.
                reader.onload = function (e) {
                    var data = "";
                    var bytes = new Uint8Array(e.target.result);
                    for (var i = 0; i < bytes.byteLength; i++) {
                        data += String.fromCharCode(bytes[i]);
                    }
                    *$scope.ProcessExcel(data)*; --I think the issue comes from this function, I might be incorrect

    $scope.ProcessExcel = function (data) {

        //file data
        var workbook = XLSX.read(data, {
            type: 'binary'
        });

        //fetch first sheet
        var firstSheet = workbook.SheetNames[0];

        //put sheet into array excelRows
        *excelRows = XLSX.utils.sheet_to_row_object_array(workbook.Sheets[firstSheet]);* -- By the time this assignment occurs, the value of the excel array for that row, is already 2/16/01

Can someone please help me understand how can this be avoided, and corrected?

Thank you,
