Changing value in Database Addon

Hello,

I use Contact Form with the extension Contact Form 7 Conditional Fields Pro and this extension Contact Form 7 Database Addon is perfect to save the forms.
But we have many variables ending with “_1” or that with several words put together with a “-” or “_”. Because the extension doesn’t work with space for the values.

Is there a way to give a more clean value to the variables with Database Addon or not ?
Example: “Description_prestation” becomes “Description of the prestation”.

Thanks by advance,
