Here's the function I wrote to export data (lists of dates and topic names for a Calculus 2 course for Fall 2012) to a calendar.
To use it: from Google Spreadsheets, go to Tools -- Script Editor... and enter in the function below (changing variable values as necessary). Save it, then execute the script from Tools -- Script Manager..., accept all the permission requests (only necessary on the first run, as in the tutorial example linked to above), and then execute this script again.
function SpreadsheetToCalendar() { // This function should be executed from the // spreadsheet you want to export to the calendar var mySpreadsheet = SpreadsheetApp.getActiveSheet(); var myCalendar = CalendarApp.openByName("Calculus 2"); // optional - delete existing events var events = myCalendar.getEvents(new Date("January 1, 2011 EST"), new Date("January 1, 2013 EST")); for (var i = 0; i < events.length; i++) { events[i].deleteEvent(); } var dataRange = mySpreadsheet.getRange("B2:C46"); var data = dataRange.getValues(); // process the data for (i in data) { var row = data[i]; // assume that each row contains a date entry and a text entry var theDate = row[0]; // First column of row var theTitle = row[1]; // Second column of row myCalendar.createAllDayEvent(theTitle, theDate); } }P.S.
