• Google Forms supports a variety of question types, including text-based, multiple-choice, grid, and date/time options, as well as static elements like images and videos.

• Forms can be designated as quizzes, allowing for assigning points, providing feedback, and enabling automated grading.

Google Forms is a cloud-based questionnaire and survey solution with real-time collaboration and powerful tools to customize form questions. Forms can also be used to create online quizzes.

You can extend Forms with add-ons that help users construct new surveys, establish connectivity to third-party systems, and integrate your Forms data with other Google Workspace applications (like Google Sheets).

You can see the Forms add-ons others have built on the Google Workspace Marketplace .

What you can do

Here are a few things you can do with add-ons that extend Forms:

• Create, access, and edit Forms using the built-in Apps Script Forms service . The Spreadsheet service lets you access the Google Sheets where form responses are stored.
• Control form behavior from an add-on using the Forms service . For example, determine whether the form is accepting responses or sends a confirmation message to respondents.
• Create custom menus and define multiple custom dialogs and sidebars interfaces using standard HTML and CSS. These UI components extend the Google Forms editor, not the form that respondents see.
• Use add-on triggers to run specified functions when certain triggering events occur. For example, form-submit installable triggers let your add-on react whenever someone submits a form response.

Form structure

A Google form is composed of a title, description, and a list of form questions. Optionally, a Form can have an associated Google Sheet where the form responses are collected.

Each form question has a type indicating the kind of information it is asking the respondent for, or a static form element (like an image or video). Each type is represented by an object in the Apps Script Forms service . Forms add-ons can use this service to add, modify, rearrange, or remove these form elements:

• Question types
  • Short answer text
  • Paragraph text
  • Multiple choice
  • Checkboxes
  • Dropdown select menus (lists)
  • Linear scale
  • Multiple choice grid
  • Checkbox grid
  • Date
  • Duration
  • Date-time
  • Time
• Static types
  • Image
  • Page break
  • Section header
  • Video

Quizzes

Forms can also act as quizzes. If you designate a form as a quiz, you can assign point values and feedback to each form question. Point values enable customized grading of the quiz. Feedback, represented by the QuizFeedback class in the Forms service , is text and links that are presented to the respondent after answering the associated form question.

Triggers

Apps Script triggerslet a script project execute a specified function when certain conditions are met, such as when a form is submitted or when an add-on is installed.

See add-on triggers for more information on what triggers can be used with Forms add-ons and what restrictions apply to their use.
