List All Users of a Google Workspace Domain in Google Sheets

The enterprise editions of Google Drive Auditor and Gmail Address Extractor use the Google Apps Admin SDK (Directory API) with Google Apps Script to create a list of all users that are part of a Google Workspace domain.

The Google Scripts gets the name and email address of users in the organization and saves the list inside a Google Spreadsheet. This script can only be executed by the domain administrator.

function getDomainUsersList() {
  var users = [];
  var options = {
    domain: 'ctrlq.org', // Google Workspace domain name
    customer: 'my_customer',
    maxResults: 100,
    projection: 'basic', // Fetch basic details of users
    viewType: 'domain_public',
    orderBy: 'email', // Sort results by users
  };

  do {
    var response = AdminDirectory.Users.list(options);
    response.users.forEach(function (user) {
      users.push([user.name.fullName, user.primaryEmail]);
    });

    // For domains with many users, the results are paged
    if (response.nextPageToken) {
      options.pageToken = response.nextPageToken;
    }
  } while (response.nextPageToken);

  // Insert data in a spreadsheet
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName('Users') || ss.insertSheet('Users', 1);
  sheet.getRange(1, 1, users.length, users[0].length).setValues(users);
}

Remember to replace ctrlq.org with your own domain address. You will need to enable the Admin Directory API under Resources > Advanced Google Services.

Then go to Resources > Cloud Platform Project, click the Project name to open the Google Developer console associated with your Apps Script project. Switch to the Library section, search for Admin SDK and enable the API.
