Automatically download google sheet as excel and send mail

You can use Google Apps Script to automate the process of downloading a Google Sheet as an Excel file and sending an email. Here's an example script that you can use as a starting point:

function downloadSheetAsExcelAndSendEmail() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var excelFile = sheet.getAs("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
  var attachment = excelFile.getAs("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
  var subject = "Daily Report";
  var body = "Here is the daily report in Excel format.";
  var toEmail = "[email protected]";
  var fromEmail = "[email protected]";
  var email = MailApp.sendEmail(toEmail, fromEmail, subject, body, {attachments: [attachment]});
}

Here's how the script works:

1. getActiveSpreadsheet() gets the active spreadsheet.
2. getActiveSheet() gets the active sheet.
3. getAs("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet") converts the sheet to an Excel file in the .xlsx format.
4. getAs("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet") gets the Excel file as a blob.
5. MailApp.sendEmail() sends an email with the Excel file attached.

To set up the script, follow these steps:

1. Open your Google Sheet.
2. Click on "Tools" > "Script editor".
3. Delete any existing code in the editor and paste the script above.
4. Replace [email protected] with the email address you want to send the email to.
5. Save the script by clicking on the floppy disk icon or pressing Ctrl+S (or Cmd+S on a Mac).
6. Set up a trigger to run the script at the desired interval (e.g., daily, weekly, etc.). To do this, click on the "Triggers" button in the left-hand menu, then click on "Create trigger" and set up the trigger as desired.

Note: Make sure to enable the "MailApp" service in your Google Cloud Console project settings. You can do this by going to the Google Cloud Console, navigating to the "APIs & Services" > "Dashboard" page, and clicking on the "Enable APIs and Services" button. Then, search for "MailApp" and click on the result to enable the service.
