Retrieving the output of a Google Apps script to local computer

Question

I'm running a Google Apps Script (based on Gmail data) and I want to save some data from Javascript to local computer. How is it possible to save/download some data, computed in Javascript here:

to a local file?

All I have found is:

var addresses = [];
var threads = GmailApp.search("label:mylabel", 0, 10);
for (var i = 0; i < threads.length; i++) {
  var messages = threads[i].getMessages();
  for (var j = 0; j < messages.length; j++) {
    addresses.push(messages[j].getFrom());
  }
}
Logger.log(addresses);

but Logger.log(...) is not very useful to save this data to local computer.

Answer 1

I propose this as an other answer.

If I got data from Google Apps Script and Google Drive, I think that Web Apps can be used for the situation. For example, it retrieves data from Google as a trigger run=ok, a following sample script can be used.

Script :

function doGet(e) {
  if (e.parameter.run == "ok") {

    // do something

    var result = "sample data"
    return ContentService.createTextOutput(result).setMimeType(ContentService.MimeType.TEXT);
  }
  return
}

You can retrieve data of result using curl on your local PC as follows. The URL is Web Apps URL.

curl -L https://script.google.com/macros/s/#####/exec?run=ok

Result :

sample data
