# Mappings UI Improvements

> These improvements to the Mappings UI builder will help you build mappings more quickly and easily.

Product: EDI platform

Stedi mappings let you transform JSON data from one shape to another, most importantly between your internal schema and EDI-like JSON required for EDI Translate. We launched the following improvements to the [Mapping builder](https://portal.stedi.com/app/mappings) UI:

- When you connect a Stedi guide to the mapping’s source or target schema, the **Guide** tab links directly to the connected guide.

- The **Schema** and **Example** tabs are now read-only when a guide is connected. This prevents you and collaborators from manually editing the schema out of sync with the connected guide.

- You can use the **View** menu to show and hide the source and output columns as needed.
