I’ve about a dozen Google sites which are just an embedded Google form with a custom script at the back.

I tried the conversion tool on a dummy site and it opened a Google doc. I am not sure how an HTML page with embedded Google form with a script will be converted to new Sites.

If you're comfortable, can you ping me on email at zito@? It's possible the custom script is the issue, but I'd be happy to take a look.
