How to add response validation to a question in Google Forms?

"what is best add-on suitable for Date validation in Google form?"- Google Docs Editors Community

Ask for an email address or a phone number and some people will type it wrong. You find out when you try to reach them. Google Forms checks answers with response validation on short answer, paragraph and checkbox questions, but not on a date, so it can't allow only future dates or only weekdays. With Formfacade, you add validation from the ⚙️ icon on the question, and people see your message before they can go on. A date question can also allow only past dates, only future dates or specific days of the week.

Create your form, or open one you have in Formfacade, and follow the steps below.

Add response validation to a question

  • On the page that opens, name your form, click Embed form and click Proceed. If you already have a form in Formfacade, open it instead.
  • Click on "Edit" tab
The tabs Edit, Preview, Share and Responses, with Edit marked
  • Click on the question
  • Click on the ⚙️ icon at the bottom of the question
An Email address question open in the editor, with the question and the gear icon marked
  • Click on the Answer tab
  • Click Configure under Validation
The Answer tab with Appearance, Prefill, Calculate and Validation, with the Answer tab and Configure marked
  • Add the required response validation
  • Click Save
For example, select Text and then Email for an email address question. This validation will check if the users are entering a valid email address format. You can enter your own message in Custom error text. When someone enters an answer that does not fit, the form shows your message and does not go on.
