# Mapping Excel Files for Control

Coherent Control adopts the same input and output mapping mechanism that is used widely on Coherent Spark. 

This mechanism allows users to map out input fields which can be edited in a locked-down version of a workbook to allow users to input data while keeping the formulas and underlying data protected.

To learn more about how to map files and maintain this protection, please review the Coherent Spark input/output mapping documentation:
