Power Query Documentation: Change Source Files

[VanNostrand]

Hi guys,

I'm trying to look for some documentation/articles addressing the changes in source files and the fact the if the structure of the files is exactly the same, Power Query will automatically apply the same previous data transformations to the new files.

But I can't seem to find anything to confirm... by any chance someone could point me to a good direction?

Many thanks!

Hi @VanNostrand ,

Check if these help.
Using Variables for File Locations

Parameters give you the flexibility to dynamically change the output of your queries depending on their value, and can be used for:

• Changing the argument values for particular transforms and data source functions.
• Inputs in custom functions.
