Google apps script Gmail get message without previous conversation

Question

I am trying to use a google apps script to dump emails that I have under a specific label to a Google Docs Spreadsheet. I want to list each email message body in a thread a

Answer 1

I was able to pull out only the body of the emails by identifying where the 'previous conversation' started.

var sheet = SpreadsheetApp.getActiveSheet();
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var LabelWithEmails = sheet.getRange(3, 2).getValue();

function getEmails() {
    clearCanvas();
    var label = GmailApp.getUserLabelByName(LabelWithEmails);
    var threads = label.getThreads();

    var row = getFirstRow() + 1;
    var firstmessageId = getfirstmsgid();
    UserProperties.setProperty("firstmsgid", firstmessageId);
    spreadsheet.toast("Loading emails..Please wait. It could take few seconds", "Status", -1);

    var messages = GmailApp.getMessagesForThreads(threads); //gets messages in 2D array

    for (var i = 0; i < 2;/*threads.length;*/ i++) {
        try {
            var messages = threads[i].getMessages();

            for (var m = 0; m < messages.length; m++) {
                var msg = messages[m];
                var isForward = msg.getBody().search(/---------- Forwarded message/i) != -1;

                if(!isValidMessage) continue;

                sheet.getRange(row, 1).setValue(msg.getFrom());
                sheet.getRange(row, 2).setValue(msg.getTo() + ";" + msg.getCc() + ";" + msg.getBcc());
                sheet.getRange(row, 3).setValue(msg.getSubject());
                sheet.getRange(row, 4).setValue(msg.getDate());

                if(!isForward) {
                    // Get only this messages body, ignore the previous chain
                    var body = msg.getBody();
                    var firstIndexOfThread = body.search(/gmail_quote/i); 
                    body = (firstIndexOfThread == -1) ? body : body.substring(0, firstIndexOfThread);

                        sheet.getRange(row, 5).setValue(getTextFromHtml(body));

                } else {
                    // Use the whole body if its a forward
                    sheet.getRange(row, 5).setValue(getTextFromHtml(msg.getBody()));
                    sheet.getRange(row, 6).setValue("***");
                }

            row++;
        }
    } catch (error) {
            Logger.log(error);
        spreadsheet.toast("Error Occured - please see the logs.", "Status", -1);
    }

    if (i == threads.length - 1) {
        spreadsheet.toast("Successfully loaded emails.", "Status", -1);
    }
  }
}
