How can we make sure the input is correct? For phone number/E-mail for example? How can we export the data of the customers to excel file?
First you can setup the input field as URL, e-mail or just Text. If you setup email there will be a validation to it. You can also setup length rules and also more advanced regular expressions rules.
What data do you want to export? All data inside a collection or all users of your site?
I want to export the data from the table which includes all the users who filled and send the form.
