function addEvents(){
var ss = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var lr = ss.getLastRow();
var data = ss.getRange("A1:C" + lr).getValues();
for(var i = 0; i<data.length;i++){
cal.createAllDayEvent(data[i][0], new Date(data[i][1]), {description:'PRO: ' + data[i][2]});
// console.log(data[i][1]);
}
}
In the past I have used
var data = ss.getRange("A1:C" + lr).getDisplayValues();
Thank you for your time
