We’ve built a free web-based converter for migrating JSON structures from Oxygen Builder 4.x to the new Oxygen 6 format.

Oxygen 6 dropped ID-based styling and switched to internal class UUIDs – so simply pasting old JSON doesn't work anymore. This tool:

maps all used classes

rebuilds the structure

and includes a lightweight WordPress plugin to re-attach styles on paste

Use case: WordPress agencies who maintain 10+ Oxygen 4 sites and need to upgrade painlessly.

Tool: https://wpconverters.com Would love feedback from other WP builder users or anyone solving similar migration problems.
