Been looking for something like this for a long time

I’ve needed a way to update forms on a live site, after modding and testing very large forms (500+ fields) on a local instance – without having to change form IDs when pushing back to live – for a long time.

I did notice on small issue, and that’s that the form with the correct ID needs to exist on a site before you can replace it. It would be nice to get something that just imports a form to a specific form ID, even if the form ID does not exist yet. So, while not exactly like ACF’s json import/export, it does a really great job of syncing local/production form fields.
