Automatically emailing info from a form submission

Here we’ll look at how to set up automatic emails, which contain information submitted by the Google Form user. The beauty of this is that the information is sent to you (and others) without you having to do anything and without you having to check the spreadsheet to see if there has been a submission. This is building on the code from my previous post, so the areas which are the same I will only briefly describe here. If you want more details see my previous post.

This is the email that we’re going to send automatically:


Here’s the full code:


Let’s look at it step by step. First, we set up the function and then get the active spreadsheet.


Then we get the sheet which contains the information we want, which in this case is on ‘Form Responses 1’.


We want to get the values on the last row, which is the latest form submission. There are 3 steps to do this. We need to get the last row on the sheet, the last column and then get the range using that information.

Line 10: We get the last row of the form responses 1 sheet (using the getLastRow method) and store it in the variable called lastRow.

Line 11: Similar to the lastRow we get the last column (using the getLastColumn method) and store it in the variable lastColumn.

Line 12: Now we want to get the values in the last row, from the first column to the last column. We do that by getting the range (using the getRange method). This takes 4 pieces of information; starting row, starting column, number of rows, number of columns). So we start on the lastRow, we start at the first column, we only want 1 row, and we want to collect data until the lastColumn. Then we add getValues to get the values in that range.


Now we have an array variable called lastRowValues which contains all the data from that last row. Now let’s assign a variable for each piece of information on that row, so that we can use the variables later in the code and so we can clearly see what’s in those variables.

Lines 15-21: Here we’re extracting a specific bit of information from the lastRowValues array, and so need to state the position of the information. The array contains this at the moment:

[29/01/2017 15:43:01], [Ian Student], [], [123456789], [Mon/Wed 17:00-18:00], [06/02/2017], [31/03/2017], [To prepare for the CAE exam.]

There’s only one line in our array, so all the values we look up will start with position [0] . Then, for example, the name “Ian Student” is at position [1] in the array (remembering that the first item is [0] in an array). So, we write lastRowValues[0][1]; to get the name.

We then repeat the same format for each piece of information we want, just changing the position in the array each time.


In lines 19 and 20, we’re getting the dates from the form submission and we could use them directly from the sheet. The problem is that they won’t be in the format they are on the sheet. They will look like this:


Not the easiest date to read and normally we don’t want the full date, so let’s change the format of the date to the way we want it. For this email, I want the format to be DD-MM-YYYY, e.g. 06-02-17.

Line 24: First I check the user has in fact inputted a date. So, I write an IF statement to check if the variable startDate isn’t empty. The If statement syntax is:

if (variable + logic) {do something if it’s true}

!== means not equal; so I’m checking to see that the variable startDate isn’t equal to empty “”. If there is a date, lines 25 & 26 are run, i.e. the parts inside the curly brackets.

Line 25: First, let’s get the month from the date and add 1. This is because January is 0, so we need to add 1 to return a real month number. We use the getMonth() method to extract the month. Then we store it in the month variable.

Line 26: Now we need to create the date format we want. There are 3 main parts, date (day number), month, and year. To get the date, we use the getDate() method, then we add a hyphen, then we add the month we extracted in line 25. Then we add another hyphen, then we get the year with the getFullYear() method. This is then stored in the startDateEdit variable. So, it will create a date like this: 06-02-2017.

Line 28: What happens if the IF statement returns false, well I want it to put a few dashes instead of a date. Here we use the ELSE statement, which has the same syntax as the IF statement and will run if the above IF statement is false. So, here I just set the variable startDateEdit as three dashes “—“.


The finish date follows the same pattern as above.


I also want to include the spreadsheet URL, so I get that by using the getUrl() method and store it is the variable urlOfSS.


Now let’s create our email with the information we’ve extracted above.

Line 44: We set up the variable message, to store the information and in the first line type a short introduction. Note, at the end of every line from line 44 to 54, we have to add a “+” to show every line is connected together, and everything is within the message variable. Also, in the email, I want to list the details, one line after another, so we use “\n ” to add a line break.

Line 46: To add the name, next to the line break we type the text “Name: ” and close it with the inverted commas. Then we need to add the variable name, putting pluses (+) either side.

Lines 47 to 54 are written in a similar way. The final line of the email, line 55, ends with a semi-colon and doesn’t have a plus.


Now, we get the email addresses from our list on the sheet called “Emails”.

Line 58: Use the getSheetByName() method to get the sheet. Then we store it in the emails variable.

Line 59: Then we get the last row of the emails using the getLastRow() method and store it in the variable numRows.

Line 60: We get the values in the range using the methods getRange and getValues.


Here it’s getting the range from row 2, column 2, to the bottom of the list of emails, and only this 1 column.


Then we set the subject line of the email. Here I’ve added a fixed part in the title “Private Class Request – ” then added the variable name, so that the person’s name of that particular request will appear in the subject line. This is stored in the variable subject.


Then we send the email using the Gmail class and sendEmail() method. Then add the 3 variables, emailTo (the email addresses), subject (the subject line), and message (our email message).


Remember to activate the onFormSubmit trigger, as explained in my last post.

As this has touched on JavaScript areas such as, arrays, if, and else statements, if you’re not confident using these, I would suggest you read the following on the excellent W3schools website:

arrays / if else

Here’s the link that let’s you make a copy of the spreadsheet I’ve used, which will copy the spreadsheet, the linked form, and which contains the above code.
