Sending email reminders for Google Sheet tasks - google-apps-script

Question

Updated the code based on suggestions below, The email does not contain the summary, any help fix this would be appreciated! The test file is attached below,
function sendEmail(){
SpreadsheetApp.getActiveSpreadsheet().getSheetByName("2021-12 {3600950}").activate();
var ss =
SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
//data on sheet, filter for any row where the status is still "assigned"
var data = ss.getDataRange().getValues()
var assigned = data.reduce(function(acc, curr) {
if(curr[5] === "assigned") {
acc.push(curr)
}
return acc
},[])
// unique list of emails
var Assignee = [0]
var Summary = [2]
var compareAssignee = []
for (i=0; i<assigned.length; i++){
compareAssignee.push(assigned[i][0])
}
//loop unique emails, all the tasks for each of those users, and send a simple email with the tasks
for (var i=0; i<Assignee.length; i++){
var Summary = assigned.reduce(function(acc, curr) {
if(curr[0] === Assignee[i])
{
acc.push(String.fromCharCode() + "pending task: " + curr[2] +
Summary[2])
//this puts a line break before each task, so when the email is
sent each one is on its own line.
}
return acc
},[])
console.log(Summary)
MailApp.sendEmail
MailApp.sendEmail(compareAssignee[0],"pending RPP task(s)",Summary[2])
}
}
function scheduleEmails(){
// Schedules for the first of every month
ScriptApp.newTrigger("sendEmail")
.timeBased()
.onMonthDay(28)
.atHour(1)
.create();
}

Answer 1

You want to send an email at the end of every month to users who have tasks that are still in "assigned" status.
The sendEmail script below finds all the tasks for each user and sends an email to them listing each of their tasks that are still "assigned". EDIT: You indicated in a comment above that emails are in Col 1, tasks are in Col 3 and status is in Col6. I updated the code to reflect that below.
Check out this sample email to see the results.
The second function creates a trigger that runs sendEmail every month. You indicated you wanted to send the email on the last day of the month, but it seems Google has a hard time with that. Some other folks came up with workarounds. I like this one: send the reminder on the 1st of the month, but at 1 in the morning! You can see more of their work here
function sendEmail(){
SpreadsheetApp.getActiveSpreadsheet().getSheetByName("status").activate();
var ss = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
//grab all the data in the sheet, and then filter for any row where the status is still "assigned"
var data = ss.getDataRange().getValues()
var assigned = data.reduce(function(acc, curr) {
if(curr[5] === "assigned") {
acc.push(curr)
}
return acc
},[])
// From all the tasks still in "assigned" status, get a unique list of emails.
var uniqueEmails = []
var compareEmails = []
for (i=0; i<assigned.length; i++){
compareEmails.push(assigned[i][0])
}
uniqueEmails = [...new Set(compareEmails)]
//loop through the unique emails, grab all the tasks for each of those users, and send a simple email with the tasks listed.
for (var i=0; i<uniqueEmails.length; i++){
var tasksPerUser = assigned.reduce(function(acc, curr) {
if(curr[0] === uniqueEmails[i]) {
acc.push(String.fromCharCode(10) + "pending task: " + curr[2]) //this puts a line break before each task, so when the email is sent each one is on its own line.
}
return acc
},[])
console.log(tasksPerUser)
MailApp.sendEmail(uniqueEmails[i],"pending tasks",tasksPerUser)
}
}
function scheduleEmails(){
// Schedules for the first of every month
ScriptApp.newTrigger("sendEmail")
.timeBased()
.onMonthDay(1)
.atHour(1)
.create();
