Migrating from squarespace to Wix while keeping formatting?

Is there any way to migrate from squarespace to wix without rebuilding all the pages? All I'm trying to do is make a grid gallery yet every time I try and drag a picture to a different spot it manages to break everything. Most times it'll mess up the entire thing and put pictures from the bottom of the list in the middle despite me not touching them, other times it will just white-screen and require me to refresh the page, losing all the changes made. I'm tired of this.
