Useful Regular Expressions for Validating Input in Google Forms


Your organization has a few vacant positions and you are planning to use Google Forms to prepare a pre-interview questionnaire for job applicants. You have created a form and it has all the standard fields where candidates can fill-in their name, email address, phone number, zip code and other information.

The form has been prepared but before you make it live, how would you ensure that candidates have entered data in the correct format? And even if the format is proper, is the data itself valid? Can you add a CAPTCHA to Google forms to prevent spam bots? Can you include a profanity filter to block people from submitting entries that include obscene words?

When you are expecting dozens, or even hundreds, of responses in your Google Forms, it is always a good idea to have some rules in place and the respondents’ data be matched against these rules even before they submit the form. For instance, if your form is asking for a person’s year of birth, and the applicant’s age should be between 25 and 50, they should only be allowed to enter a number between 1970 and 1996 in the year of birth field.
