How to send email from a spreadsheet - google-apps-script

Question

I have a spreadsheet on Google Docs with tasks for a job that we are working on at work. What I am wanting it to do is to send the whole row to the intended recipient but I can only get it to send the info from the first column after the email address. Everything has a due date on it and I would like to get it to send a reminder when it gets close to that date but I do not know how to do that.
Any help would be greatly appreciated.
Here is the code I have right now:
function sendEmails() {
var sheet = SpreadsheetApp.getActiveSheet();
var startRow = 3; // First row of data to process
var numRows = 2; // Number of rows to process
// Fetch the range of cells A2:B3
var dataRange = sheet.getRange(startRow, 1, numRows, 2)
// Fetch values for each row in the Range.
var data = dataRange.getValues();
for (i in data) {
var row = data[i];
var emailAddress = row[0]; // First column
var message = row[1]; // Column B, Column C, Column D, Column E, Column F, Column G
var subject = "Email Test Spreadsheet";
MailApp.sendEmail(emailAddress, subject, message);
}
}

Answer 1

when you define your dataRange like this :
var dataRange = sheet.getRange(startRow, 1, numRows, 2)
you read data from startRow column 1 for numRows but only 2 columns (the last value is 'width') so you could easily modify your script to get all the columns you want just by changing this last value. Then using row[i].toString(), you will get your comma separated fields.
Then you might want to get a better presentation using HTML format to present data in a table for example but this is outside the point of your question ;-)

Answer 2

When you define a data range like this
var dataRange = sheet.getRange(startRow, 1, numRows, 2);
you are taking the data from A3:C5
you can also refer to the documentation
If you can post a sample spreadsheet as per the description of your problem, then it will be helpful for others to help you.

This piece: var message = row[1]; will only ever get the second element (index 1) in the array. You'll need to iterate through the row to get all the array elements.
var message = row[1];
message.concat(row[2]);
message.concat(row[3]);
And so on. Or you could build a loop.

And to get the range, why do it the hard way? sheet.getRange("A2:B3");
That's the range you said you're trying to get in the comment above that line, although it is only 4 cells. sheet.getRange("A2:G3") would get two rows out to column G.
Of course, if you add rows to the sheet, you'd have to modify the code every time.
Instead, try this.
var bottomRow = sheet.getLastRow();
var rangeInA1 = "A2:G"+bottomRow;
var dataRange = sheet.getRange(rangeInA1);
