This is real use case for Power Query through an example. In this example you will learn how custom functions can be used with parameters to expand a data transformation applied on a CSV file to all files under a folder. The solution implemented with this method can be refreshed and pick the new data set anytime a new file appears in the source folder. You will learn how to apply simple data transformation in Power Query, how to change the whole transformation set to a function utilizing a parameter, and how to search through files in a folder, and apply function on all files and combine the whole result set.
