How to delete all rules from CSS?

I have a file with CSS, for example like this
.how-vip{position:relative;max-width:1230px;width:100%;margin-left:auto;margin-right:auto;padding:80px 30px;}
.how-vip__text{font-size:16px;line-height:1.6;color:#fff;text-align:center;padding:60px 190px;font-family:Montserrat-Medium;}
.how-vip__button{background:-webkit-linear-gradient(right, #eb5981 0%, #ffbd52 100%);background:linear-gradient(to left, #eb5981 0%, #ffbd52 100%);width:225px;display:block;border-radius:999px;border:none;font-family:Montserrat-Semibold;font-size:18px;height:56px;line-height:56px;text-align:center;color:#000;margin:0px auto;margin-bottom:60px;}
.how-vip__button:hover{border:1px solid #ee667b;background:none;color:#ee667b;line-height:54px;}

How do I go to erase everything in everything between the braces, i.e. to the whole file turned into a column of the form:

Ie, make procurado thousands of rows.
