Ever considered how helpful it would be to predefine the format in which your survey respondents reply to an open-ended question? Validating open-ended input in your Surveypal surveys can be done using RegEx.
What is RegEx or Regular Expression?
A RegEX is a text pattern formed by a sequence of characters. Regular Expression is used to check if the input matches a prespecified pattern.
If, for example, you want you respondents to input their license plate numbers, you can just apply a RegEx pattern to that particular survey open-ended question.
When should I apply Regular Expression in my survey questions?
Validating respondent input using RegEx is a no-brainer as it enables you to collect data in the right format and significantly lowers the possibility for user errors. Apply regular expression in your survey questions when you seek data input in a specific format such as
- Phone number
- Email address
- Zip code
- Date
- License plate number
- Social security number
- IBAN
- ISBN number, and more
