Convert Google Sheet to CSV then attach it to an email - google-apps-script

Question

I have a simple Apps Script need, but can't find a near enough sample from the community.
I need to convert 2 sheets from a Google Spreadsheet, individually, as CSV files then attach them in an email.
So far, I found a script to convert a sheet into a CSV format and file it in a folder.
I looked for a script to add that will instead attach the CSV file to an email, but can't find anything which I can use based on my novice level of Apps Script knowledge.
Any help will be greatly appreciated. Thank you very much.
Script:
function sheet1ToCsv()
{
var ssID = SpreadsheetApp.getActiveSpreadsheet().getId();
var sheet_Name = "xxxx"
var requestData = {"method": "GET", "headers":{"Authorization":"Bearer "+ScriptApp.getOAuthToken()}};
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheet_Name)
var sheetNameId = sheet.getSheetId().toString();
params= ssID+"/export?gid="+sheetNameId +"&format=csv"
var url = "https://docs.google.com/spreadsheets/d/"+ params
var result = UrlFetchApp.fetch(url, requestData);
var folderId = "yyyy";
var csvContent = {
title: sheet_Name+".csv",
mimeType: "application/vnd.csv",
parents: [{id: folderId}]
}
var fileJson = Drive.Files.insert(csvContent,result)
}

Answer 1

In your showing script, an email is not sent. And, only one CSV file is created to Google Drive. From I need to convert 2 sheets from a Google Spreadsheet, individually, as CSV files then attach them in an email. and your showing script, when your showing script is modified, how about the following modification?
Modified script:
function myFunction() {
var emailAddress = "###"; // Please set your email address.
var sheetNames = ["Sheet1", "Sheet2"]; // Please set your 2 sheet names you want to use.
var ss = SpreadsheetApp.getActiveSpreadsheet();
var ssID = ss.getId();
var requestData = { "method": "GET", "headers": { "Authorization": "Bearer " + ScriptApp.getOAuthToken() } };
var blobs = sheetNames.map(s => {
var params = ssID + "/export?gid=" + ss.getSheetByName(s).getSheetId() + "&format=csv";
var url = "https://docs.google.com/spreadsheets/d/" + params;
return UrlFetchApp.fetch(url, requestData).getBlob().setName(s); // <--- Modified
});
MailApp.sendEmail({ to: emailAddress, subject: "sample subject", body: "sample body", attachments: blobs });
}
When this script is run, an email is sent by including 2 CSV files as the attachment files.

function myfunk() {
const folder = DriveApp.getFolderById("folderid");
const ss = SpreadsheetApp.getActive();
const names = ["Sheet1", "Sheet2"];
const params = { "method": "GET", "headers": { "Authorization": "Bearer " + ScriptApp.getOAuthToken() } };
let bA = [];
names.forEach(n => {
let sh = ss.getSheetByName(n);
let url = "https://docs.google.com/spreadsheets/d/" + ss.getId() + "/export?gid=" + sh.getSheetId() + "&format=csv";
let r = UrlFetchApp.fetch(url, params);
let csv = r.getContentText();
let file = folder.createFile(n, csv, MimeType.CSV);
bA.push(file.getBlob());
})
GmailApp.sendEmail(recipient, subject, body, { attachments: bA })
}
