The best way to loop through the rows of an excel file using exceljs is using the builtin method .eachRow()
var Excel = require("exceljs");
var workbook = new Excel.Workbook();
workbook.xlsx.readFile("./CIoT_External Libraries & 3rd Party Content.xlsx" )
.then(function(data){
var worksheet = workbook.getWorksheet("WPA ext libs 2017.10.05");
worksheet.eachRow(function (row, rowNumber){
// row_values contains the values, (first column is indexed by
var row_values = row_1.values;
// Now you can access the columns directly by the column index
Console.log("Value of Column B is : "+ row_values[2])
}
});
