How to send conditional email alert on google sheet? - google-apps-script

Question

I'm setting up an email alert on my google sheet, in which if a value in one column goes below 2 I get an email alert on my mail.
I have mulitple domains and it is very tedious to check the domains expiry date every day. I created a sheet in which I put up domain name, registrar,hosted, todays date, expiry date, Expiry remaining days. Now I want to create an alert on "Expiry remaining days column", so that when the remaining days is below 2 days it send an alert email to my list of email addresses.
What I have already done is getting an email for one cell value but what I want to do is get it on whole column or number of column values.
function CheckSales() {
// Fetch the values
var domainexpireRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("domain list").getRange("F2");
var domainexpire = domainexpireRange.getValues();
// Check domain expiring
if ( domainexpire < 2){
var emailRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Company emails").getRange("B2:B4");
var emailAddress = emailRange.getValues();
// Send Alert Email.
var message = '2019 smtp Domain Expiring in two days. Please check the sheet domain sheet '; // Second column
var subject = '2019 smtp Domain Expiring';
MailApp.sendEmail(emailAddress, subject, message);
}
}
I have a sheet which has multiple rows and columns, what I want to do is check column F and if any of the value on column F is less than 2 then send an alert email to my email addresses.
My code is working fine if I copy paste the code to multiple times and change the "getRange("F2");" to F2,F3,....F100 .
But it is not good way to put up a code. Can anyone tell me if I can edit some code and get the result.
I tried using "getRange("F2:F");" & getRange("F2:F54");but it doesn't worked out.
Thanks for your help.

Answer 1

Try using a for statement to loop through the whole sheet, the one below should work:
function checkSales() {
// Fetch the values
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var sheet = spreadsheet.getSheetByName("domain list");
var dataRange = sheet.getDataRange();
var data = dataRange.getValues();
// loop through each row starting at row 2
for (var i = 1; i < data.length; i++) {
var domainExpire = data[i][5];
// Check domain expiring
if (domainExpire < 2) {
var emailRange = spreadsheet.getSheetByName("Company emails").getRange("B2:B4");
var emailAddress = emailRange.getValues();
// Send Alert Email.
var message = '2019 smtp Domain Expiring in two days. Please check the sheet domain sheet '; // Second column
var subject = '2019 smtp Domain Expiring';
MailApp.sendEmail(emailAddress, subject, message);
}
}
}

Try this:
function CheckSales() {
var ss=SpreadsheetApp.getActive();
var sh=ss.getSheetByName('domain list');
var domainexpireRange=sh.getRange(1,6,sh.getLastRow()-1,1);
var domainexpire=domainexpireRange.getValues();
for(var i=0;i<domainexpire.length;i++) {
// Check domain expiring
if (domainexpire[i][5]<2){
var emailRange=ss.getSheetByName("Company emails").getRange("B2:B4");
var emailAddress=emailRange.getValues().map(function(r){return r[0];}).join(',');
// Send Alert Email.
var dateString=Utilities.formatDate(new Date(), Session.getScriptTimeZone(), "yyyy");
var message=Utilities.formatString('%s smtp Domain Expiring in two days. Please check the sheet domain sheet.',dateString);
var subject=Utilities.formatString('%s smtp Domain Expiring',dateString);
MailApp.sendEmail(emailAddress, subject, message);
}
}
}
