google-apps-script GmailApp Get CSV file attached to a mail
Example
Assume that we have a system that sends out daily reports over email in the form of attached CSV files and that we want to access these.
function getCsvFromGmail() {
// Get the newest Gmail thread based on sender and subject
var gmailThread = GmailApp.search("from:[email protected] subject:\"My daily report\"", 0, 1)[0];
// Get the attachments of the latest mail in the thread.
var attachments = gmailThread.getMessages()[gmailThread.getMessageCount() - 1].getAttachments();
// Get and and parse the CSV from the first attachment
var csv = Utilities.parseCsv(attachments[0].getDataAsString());
return csv;
}
