How do i control the text response with a regex expression where a user enters the information in capital letters?

Hi @ericka_ochoa,

Welcome to the community! You could do the same as discussed in the post discussed previously:

Restrict an entry with upper case and special characters while entering a form

Hi @PEHAN, Welcome to the community! You could do the same following the instructions outlined below: In the survey tab of your xlsform: [Image 1] Data entry screen as seen in Enketo: With a wrong entry [Image 1] Data entry screen as seen in Enketo: With a correct entry [Image 2] Reference xlsform: UPPER CASE (Regex).xlsx (10.1 KB) Have a great day!

This discussion should also be helpful:

Uppercase format

Hi @danielarodriguez, If you wish to capture a Name & Surname both in uppercase please type regex(.,’[A-Z]{1}[a-z]{1,50}[ ]{1}[A-Z]{1}[a-z]{1,50}’) under the constraint column of your xlsform. Please note that you are able to type only 50 characters for Name and another 50 character for Surname. If you wish to have a much more longer one increase the number to your desired one.

In addition to the post discussed previously you could also have a look at our support article Restricting Text Responses With Regular Expressions. It should be more helpful as it attempts to capture a wide range of examples.

Have a great day!
