    Apostrophe Forms Google Sheets Submission

    For use with ApostropheCMS 2.x. Requires Node v8 and apostrophe-forms v1.x.

    This module adds an additional form submission option to Apostrophe Forms. It allows website managers to configure individual forms to submit to a specific Google spreadsheet. The sheet must exist, but does not necessarily need to be set up with column headings before use. If you wish to set column headings directly (e.g., to set the order of columns yourself), those column headings must exactly match the field name from the Apostrophe form.


    Create API project

    1. Create a project in the Google Cloud Platform API console. Enable the Google Sheets API on the project in the API Library.
    2. Create an API service account in the Google API Console service.
    3. Save the credentials JSON file provided with the new service account. You may not be able to download this again. Add this file to the lib/modules/apostrophe-forms directory in your Apostrophe project as credentials.json.
    4. Note: We do not recommend committing this file to version control if your code is public, in which case you should so add it to the .gitignore file (for Git) and put it directly on your production server. Alternately you can provide the file as JSON in an environment variable named GOOGLE_APPLICATION_CREDENTIALS.
    5. Copy the service account email address. You will need to add this as an "Edit"-level user on your Google spreadsheet as you would a human editor.
    6. Plan for the service account credentials to expire in 10 years. The service account credentials have a long life span, but it is not infinite.

    Create your spreadsheet.

    1. This can be done later by CMS users as well. There is help text in the UI directing them to make note of the spreadsheet ID and sheet name.
    2. Column headers in the Google spreadsheet must match the form field names (not the field labels), or else the module will add new columns to the spreadsheet.

    A warning about editing the spreadsheet

    Please note that you must not add any empty, unlabeled columns to the spreadsheet once submissions begin. Due to the rules of Google's spreadsheet API the gap will be considered as the start of a "new table" and newly appended rows will start at that column, which is probably not what you want. If this does happen, move the data over and add a header to the empty column.

    Configure the module

    Enabled the module in your Apostrophe app.js file with other modules.

    // in app.js
    modules: {
      // ...,
      'apostrophe-forms': {},
      // ... Other Apostrophe Forms modules and configurations
      'apostrophe-forms-submit-google': {},

    Note on dates and times

    "Date Submitted" and "Time Submitted" columns are added automatically. These are always in UTC (Coordinated Universal Time).

    Modifying the submission before it is sent to Google

    If you wish to modify the submitted data just before it goes to Google, for instance to add a new property, you can catch the apostrophe-forms-submit-google:beforeSubmit event. Let's say we want to create a "unique key" column based on the date submitted, time submitted, and an email field in the submission:

    // In the index.js of your own module
    module.exports = {
      construct: function(self, options) {
        self.on('apostrophe-forms-submit-google:beforeSubmit', 'addUniqueKey', async (req, form, data) => {
          data['Unique Key'] = data['Date Submitted'] + data['Time Submitted'] +;

    The submitted spreadsheet rows will now include the additional column.

    Issues with column formatting

    This module sends data to Google Sheets "as entered," i.e. as if the it were typed by the user in Google Sheets. In most cases this does good things: dates are detected as dates, times as times, numbers as numbers, etc.

    However in certain cases, the results may be surprising. For instance, a phone number with a leading 0 and no spaces or punctuation will lose its leading 0 because this is the standard behavior of Google Sheets when it believes it has detected a number. Google does not store the zero in this situation, it is truly gone.

    Fortunately you can correct this by formatting the column correctly in Google Sheets. Open the sheet, select the column that will contain phone numbers, and select "Format -> Number -> Plain text". Leading zeroes will not be removed from future submissions.
