Using parameters

Parameters are a vital component of custom functions in Power Query. They allow you to create dynamic and flexible functions that can be adapted to different datasets and scenarios. In this section, we will introduce parameters, exploring the types of parameters available, how to define them, and best practices for their use.

Types of parameters

Power Query offers several types of parameters that you can use in your custom functions:

• Text parameters: These parameters accept text input, such as column names or descriptions
• Number parameters: Number parameters accept numeric values
• List parameters: You can create lists of values that users can select from
• Table parameters: Table parameters accept tables as input, allowing for more complex data structures
• Function parameters: You can even pass functions as parameters to create dynamic behavior
