# Building schemas from JSON

We’ve introduced a faster way to define and edit complex data structures in step properties, callables, config, and API schemas: **Building schemas from JSON.**

* **Step Properties**: Quickly generate objects and arrays by pasting JSON.
* **Callable Workflows & APIM Schemas**: Easily create input/output schemas with a JSON sample.
* **Project Config**: Edit your configuration directly with the new *Raw JSON*\*\* \*\*tab.
