Validating end-user input values

[Shmuel_Preiszle]

I’m new to Airtable, and have been browsing the help center and playing around with the features. One thing I didn’t see mentioned anywhere was input validation. For instance, for a numeric field requiring the value to be less than, greater than, or between values-- as an age field which must be 21 or greater. Or a date field which must not be a future date. Or a currency field limited to 10000. An so on.
How would these be done in Airtable ?

Welcome to the community, @Shmuel_Preiszler! :grinning_face_with_big_eyes: In-field validation isn’t currently available in Airtable. The only way to pseudo-validate inside of Airtable itself is to provide feedback in another field using a formula. However, this won’t work with forms because formula fields can’t appear in forms, and Airtable forms also don’t provide native validation options. Another option is to use a third-party form tool like JotForm, which can validate input before the data is sent to Airtable.

We built an input validation solution in miniExtensions Form. You can set it to validate against another formula field in your table or even use Regex. Here's a condition example where 'Age' is required to be 21 or greater.
