# Modify Data

You can use Freshpaint's transformation dashboard to set up a transformation to modify data.

To get started, navigate to the [Transformations page](https://app.freshpaint.io/transformations) on your dashboard, and then click "Create New"

Select "Modify Data" (if you want to map your events to standard events, you can follow the guide [here](/admin-panel/transformations/standard-events.md)) as your transformation type.

Choose the Freshpaint event and the destination that you want to modify event data for. Transformations can be applied to the following:
