Spreadsheet to Form no case-sensitive

Ciao, c'è un modo per rendere il widget Spreadsheet to Form presente nella prima padgina no case-sensitive?
Ho inserito nel form le righe di CSS:

#access-code {

 text-transform: uppercase; !important;

}

ma non funziona perchè anche se scrivo in lowercase la formula trasforma il testo in uppercase ma va cmq a ricercare il codice univoco in lowercase e non riesce a trovarlo.

Come posso risolvere il problema?

Grazie mille.

Hi jackshepard3183,

Thanks for reaching out to Jotform Support. I'd like to let you know that I am using a translation tool to provide assistance but if you would prefer to get assistance in Italian language, we can forward your ticket to our Italian team. However, please note that it could take longer to receive a response. 

Unfortunately, this is not currently an available feature. Using a CSS code will only change the appearance of the text. I recommend using codes or numbers as access codes for the Spreadsheet to form widget. While the feature you’re looking for isn’t currently available, rest assured we’re always working to add new services and features to Jotform. 

I've gone ahead and escalated your request to our Developer Team. When or if it's developed depends on their workload, how viable it is, and how many other users request it. If there are any updates, we’ll circle back to this thread and let you know.
