# Custom fields

Supermetrics Custom fields let you transform the data you use in your reporting. How the data is transformed is up to you — once you've created a Custom field, it's saved and ready for use whenever you need it.

As the name suggests, Custom fields are entirely customizable and offer opportunities for deep analysis and modification, such as:

- Create new fields for missing data from a data source.
- Make bulk changes, such as corrections or formatting adjustments, quickly and efficiently.
- Manipulate metrics and dimensions to tailor strategies for better audience engagement.
- Optimize campaigns for higher performance.
