Hey there! I just wanted to add that our miniExtensions form allows for regEx validation of input fields without the need for any extra fields. ChatGPT is really good at generating regEx these days, so you don't really have to know much about it. Just describe your desired format and maybe have it tweak the results a couple of times to get the desired functionality. Using regEx, you can force the input to be in any specific format you need!

Using this in the miniExtensions form is super easy. You just set up your field and add the "matches regex" condition to the field's validation settings! The form will then only accept submissions with valid values according to the regex that's provided and show an error if it the condition is not met!

You can try this out now by creating a free account! 🙂
