Text in Proper format

Dear colleagues:
Is there a method to restrict people to write the text in xlsform in proper format like excel (only first letter is in Upper case)

Hi @Moteb_Marei

you can try regex https://docs.opendatakit.org/form-regex/

Hi @Grzesiek2010
Thanks for your answer, I have another issue:
to let people enter numbers like this:
01,02,03,........,10,11,..... etc so no single inputs
is there any idea?

You can also use regex in that case.

Hi @Grzesiek2010
Thank you I used string-length(.) >=2 it works.
is there any method when people enter string words in any case they want but on the export or on the server we need to show them in upper case
so only the view will be in upper case not entring

You might be able to use a calculate type question, and if the string length of their answer is 1 then prepend a 0.
