Efficient Input Validation with Regular Expressions in Google Forms

Efficient Input Validation with Regular Expressions in Google Forms

Have open openings in your company and want to create pre-interview questions using Google Forms? Using common fields like name, email, phone number, and zip code, you have created a form. But how can you be sure the data follows the right format before you deploy it? Is the data itself valid even if the format is correct? Are you considering implementing a CAPTCHA to prevent spam bots or a filter to remove vulgar language?

Having predetermined criteria might help you save time when your Google Form is expected to get a flood of answers. It is a good idea to check your data against these guidelines before submitting it. Consider that your application asks for the applicant’s birth year. Only the period between 1970 and 1996 is allowed if the age should fall between 25 and 50.

Regular Expressions in Google Forms:

Regular Expressions (regex or regexp) in Google Forms make it easier to construct complex validation criteria. Think of them as patterns that are compared to with each entry in a form field. Submission only takes place when the pattern matches user input.

Let’s use an illustration to show this. Consider a form where the user’s birth year is requested. Access the “Data Validation” portion of the form field while designing the form. Make “Regular Expression” your selection in the menu. Select “Matches” and enter the following regex:

^19([78]\d|9[0-6])$

The field now only accepts values between 1970 and 1996, excluding values between 1977 and 1995.

https?://(www.)?youtu(.)?be(.com)?/.*(?v=|/v/)?[a-zA-Z0-9_-]+

Character Limit: Set a character limit of 140, which is appropriate for short inputs.
