How to save input data of form fields in uppercase in the excell sheet?

Hi, how can i save some fields in uppercase?

the css only makes visual changes during the registration, i need a real modify of some fields for the excell sheet.

Can you help me with this? i saw in other posts that i cant directly add javascript in the form. I don't embed the form in website so i don't need a copy of the source code. i need to change the original source code or i need another way for solve my problem

Unfortunately it is not possible to change the input data of form fields in upper case and save it in submissions. We can inject custom css code in form to change the text to uppercase but it will only be displayed in form field but the data will be saved in original format in which user input.

The only option available to achieve your requirement is by downloading your form's full source code and adding custom javascript code. Please note the updated form source code cannot be uploaded back to JotForm and you will have to host the form's source code in your own server / website. The following guide should help you how to download your form's source code:    https://www.jotform.com/help/104-How-to-get-the-Full-Source-Code-of-your-Form
