Validating response text in a Google Form with Regex in Google App Script

Question

I would like to validate the response text with Regex, being aware that it can be done manually (https://www.labnol.org/internet/regular-expressions-forms/28380/).

However, as we are building the forms with Google App Script, I am trying to use FormApp.createTextValidation() to construct the validation needed. There are many different methods available (https://developers.google.com/apps-script/reference/spreadsheet/data-validation-builder), but they seems to be all pre-set. As we may have very specific validation formats, we need to write our own regex to validate the response. Is that possible?

Thanks a lot in advance!

Answer 1

The second link applies to spreadsheets, not to forms. Instead of that link you have to look into Class TextValidationBuilder, more specifically

• requireTextContainsPattern(pattern)
• requireTextDoesNotContainPattern(pattern)
• requireTextDoesNotMatchPattern(pattern)
