Google Apps Script - Send Email based on date in cell

Question

I\'ve looked around and have bits and pieces but can\'t put the puzzle together. I\'m attempting to create a script that will run on a trigger configured to run daily. The

Answer 1

I would do it this way ....

Setup the spreadsheet like this: https://docs.google.com/spreadsheet/ccc?key=0AkGlO9jJLGO8dDJad3VNTkhJcHR3UXlJSVRNTFJreWc

Change the code to:

function sendEmails() {
  var spreadsheet = SpreadsheetApp.openById('Type spreadsheet key here from spreadsheet URL');       
  /// e.g.  var spreadsheet = SpreadsheetApp.openById('0AkGlO9jJLGO8dDJad3VNTkhJcHR3UXlJSVRNTFJreWc');     

  var sheet = spreadsheet.getSheets()[0]; // gets the first sheet, i.e. sheet 0

  var range = sheet.getRange("B1"); 
  var dateString = new Date().toString();
  range.setValue(dateString);   // this makes all formulas recalculate

  var startRow = 4;  // First row of data to process
  var numRows = 50;   // Number of rows to process
  // Fetch the range of cells
  var dataRange = sheet.getRange(startRow, 1, numRows, 4)
  // Fetch values for each row in the Range.
  var data = dataRange.getValues();   

  for (i in data) {
    var row = data[i];
    if( row[3] == true) {
      var emailAddress = row[0];  // First column
      var message = row[1];       // Second column
      var subject = "Task Item Due";
      try {
          MailApp.sendEmail(emailAddress, subject, message);
      } catch(errorDetails) {
        // MailApp.sendEmail("eddyparkinson@someaddress.com", "sendEmail script error", errorDetails.message);
      }

    }
  }
}

The trigger:

Because of the trigger, you will need to open the spreadsheet using openById. To do this, in the code replace 'Type spreadsheet key here from spreadsheet URL'. To find the key, open the google docs spreadsheet, the link has "key=A0a0df..." paste the code. See the example.
