Field validation is really useful as it lets you gather the data only in the format that meets your requirements. For each type of field, you can find in the left side panel under Validation section the available restrictions you can place on that specific field. Below you can find the available field validation in our form builder:
Number/Formula/Price → numeric, numeric plus (for numbers with decimals)
Email → email format
Link → URL, page must start with https
Date → mm/dd/yyyy; dd/mm/yyyy; yy/mm/dd; mm/yyyy
Time → 12 hours/24 hours
Phone → numeric, by default 3-3-4, but there are various choices (2-2-4, 2-3-4, 2-3-8, etc)
For Short answer field, there are more complex validations available:
alpha – only letters
numeric – only digits
alpha numeric – letters and digits
alpha space – letters and white spaces
alpha numeric space – letters, digits, and white spaces
full name – e.g. John Doe – the value must contain at least one space character
regular expression – add a regex code to define your own validation code (the regex has to start and end with a forward slash: “/”)
