Google App Script. Retrieve emails list from the sheet - google-apps-script

Question

In the following script I have to manually insert the email addresses. I rather get the list from the sheet to be able to update it without editing the script.
How do I retrieve a list of email addresses from the sheet (Sheet!A2:A)?
function sendReport() {
EMAIL = 'email'
URL = 'url'
+ '/export?'
+ 'format=pdf'
+ '&size=A4'
+ '&gid=id'
+ '&scale=4'
+ '&portrait=true';
SpreadsheetApp.getActive();
var response = UrlFetchApp.fetch(URL, {
headers: {
'Authorization': 'Bearer ' + ScriptApp.getOAuthToken()
}
});
var message = {
to: EMAIL,
subject: "subject",
body: "body",
attachments: [response.getBlob().setName('file.pdf')]
}
MailApp.sendEmail(message);
}

Answer 1

Is the script you expect as follows?
Modified script:
function sendReport() {
URL = 'url'
+ '/export?'
+ 'format=pdf'
+ '&size=A4'
+ '&gid=id'
+ '&scale=4'
+ '&portrait=true';
var response = UrlFetchApp.fetch(URL, {
headers: {
'Authorization': 'Bearer ' + ScriptApp.getOAuthToken()
}
});
// Retrieve values from Spreadsheet.
var sheet = SpreadsheetApp.getActiveSheet();
var values = sheet.getRange("A2:A" + sheet.getLastRow()).getDisplayValues();
// Send the email using the email addresses.
values.forEach(([email]) => {
if (email) {
var message = {
to: email,
subject: "subject",
body: "body",
attachments: [response.getBlob().setName('file.pdf')]
}
MailApp.sendEmail(message);
}
});
}
If you want to set the specific sheet, please modify var sheet = SpreadsheetApp.getActiveSheet(); to var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1");.
