The actual CSS code might be different depending on your site’s theme. If you want to try the code You can add that CSS snippet below, on **My Site > Customise > Additional CSS**.
/* Transform coupon code into Uppercase*/
input#coupon_code {
text-transform: uppercase;
}
If that doesn’t work you can write back to us and share your site’s ULR so that we can review the Coupon form and help you customizing the CSS snippet.
I hope this helps and points you in the right direction!
Cheers!
